Hello everyone

.
Going to cap off this thread with discussing three things; the Sun/Moon Metal's, the differences between the SD & HD versions, and the DLC Packs that the HD versions got.
Sun and Moon Metals:
Remember power stars in Super Mario 64? Now take the fact the game made it clear you had to get these and multiply the frustration with level-caps for each zone based on your metal level and you have the metal system here.
This isn't an issue, if you are an explorative gamer who searches everywhere for items in the levels. But the Day levels were not designed for this kind of hunting

.
Between the camera not responding and level design clearly tunnel focused, getting all the metals in the Day Stages is not a fun experience.
The Night levels its a lot better, as you are already trained to think "I'm not running, so I'm taking my time looking for things", so hunting for every metal in the night levels isn't an issue. In fact, between exploring the hub world, keeping a sharp eye during day levels and trying to get every metal during night stages makes this a non-issue.
.....But out of my four issues with Unleashed, this is my biggest problem. It creates an artificial level cap for the game and if you just want to run though everything, it creates really annoying backtracking X(. I can defend a good deal of this game, but the Metal system is something I cannot defend at all.
It sucks and it is a big issue with Unleashed.

Wii/PS2 vs. PS3/360:
This is interesting, as Unleashed wasn't a PS3/360 only game, as it came out on the Wii and PS2 (that's right, it came out on PS2 XD) as well.
There are a lot of differences between the versions and will make a simple chart to help point out the difference.
Wii/PS2 Version:
-More Werehog stages (1 in HD version vs. the 3-5 in the SD version)
-Werehog combat very different; no combos and focus on button/motion control mashing
-Day Levels completely different, designed by Dimps (who made the Sonic Rush series)
-Mazuri and Empire City's stages (Day and Night) cut from the SD version
-Werehog focused more on platforming then combat in SD version
-Hub worlds are replaced with Gaia Gates to explore. Clearing levels with S Ranks unlock Sun/Moon metals which can unlock more lives, concept art, music and more.
-Eggmanland is much easier compared to HD version
-No Upgrade system for Day Levels; Boost Meter upgrades within the levels as you collect more rings. Night levels have more streamlined upgrade system.
The Wii version does look nice at points and its impressive seeing it in action

.
One poster did a really great job commenting on the Wii version, so here is his post! Blaze Hedgehog covers the Wii version in excessive detail, so hope this helps everyone interested in getting the Wii version or not.
People who prefer the Wii version
are crazy people.
Stage hubs were replaced with menu screens where you have to move a cursor around and talk to NPCs that way. Unlike the HD version where you can skip talking to 95% of the people in the game, the Wii version requires you to talk to everyone before you can advance.
The whole structure of the Wii version has been rebalanced. In the Wii version, you are no longer required to collect Sun or Moon Medals to progress through the game, and largely, they are only awarded for doing well in stages themselves. In the HD version, Sun and Moon Medals are collectables you find in stages and some levels require certain numbers of medals in order to be accessed.
In the Wii version, Sonic's boost meter "levels up" and grows longer depending on how many rings you collect. In the Wii version, the boost meter is broken down in to segments, and each time you press the boost button, you deplete one entire segment (like that Ridge Racer PSP game). In the HD version, your boost meter is a fixed length that can be upgraded in the hub worlds using EXP gained in levels. When you boost in the HD version, there are no segments to your boost meter and you can stop boosting whenever.
In the HD version, Werehog levels were big, long, 15-20 minute stages. In the Wii version, Werehog levels have been broken down in to 4 smaller, individual levels, each one usually lasting 5-10 minutes. Even though it's four separate Werehog stages, you usually end up playing all four in a row, back to back, so it's roughly the same amount of Werehog regardless of what version you're playing.
Savannah Citadel (Africa) and Skyscraper Scamper (New York) are not present in the Wii version. I think you visit those places on the map, but there are no levels associated with those locations. You do, however, face bosses there. It's weird.
Levels are completely different. Controls are completely different. I find the Wii version to feel a lot more "stiff" than the HD version. Combat as the Werehog in the Wii version is significantly worse; combat doesn't flow at all and there are barely any combos to work with.
Compare for yourself:
Jungle Joyride Day - Wii
Jungle Joyride Day - Xbox 360
Rooftop Run Night - Wii
Rooftop Run Night - Xbox 360
PS3/360 Versions:
-Far more moves for the Werehog
-Greater focus on Day Sonic's levels with many optional missions to complete, extra acts to unlock and DLC that you can buy (for both Day and Night)
-Night levels have better balance between combat/platforming
-Night level platforming more rewarding then Wii version
-Controls better in HD version
-Eggmanland very challenging and far different from SD version
-Hubs more expanded in HD version. Small hubs to walk around in and Entrance Stages that house act gates and extra goodies to find.
-Supported with DLC; 7-8 DLC packs for both HD versions that expand the content from the base game. Makes the ratio of Day and Night stages a lot more fair (with equal amounts with all DLC purchased).
As someone who fully beat both versions........HD version hands down. The Werehog is a massive improvement over the Wii/PS2 version and I hated the fact there was such a pitiful amount of Day content in the Wii version. The Metal System is a big issue in the Wii version but at least we get a good amount of Day & Night levels, not the former having small amounts of stages while the latter makes up 70% of the damn game X(.
I'm sorry but I really don't like the Wii version. Would like how it handles the Metals though (making you get perfect runs even more rewarding for both Day and Night).

DLC Packs:
Unleashed was the first Sonic game to get substantial amounts of DLC and they are interesting.
Most of the levels in every pack are just hard versions of stuff that is in the base game....but some of them are a lot of fun. Night Stages with a great focus on platforming, Day Levels playing with new mechanics and locations not in the original levels, and it some of the hard-mode levels being somewhat enjoyable.
I liked the DLC but it isn't amazing or anything.

Overall thoughts on Unleashed are positive. I think this is a great game despite my four major gripes and I feel the HD version was a great step in the right direction for the series. It has issues and they range from minor to horrid depending on your preference but overall, I really liked this game

.
My next venture in the Sonic series is going to be a game I never played before, so hope you all look forward to it
