Of the current gen systems, I own a Wii, DS, Ps3 and a decent spec PC. (My 360 died two years ago.) I also play a lot of games. And everything considered, Conduit 2 is a contender for my favourite FPS of the year.
I've read through this whole thread and I find the negativity coming from some people absolutely astounding. I've poured more than 20 hours into Conduit 2 so far, which breaks down to about 12 hours off-line multiplayer, 3 to 4 hours single player, and the rest on-line. At present only two negative aspects stand out for me. Firstly, the casting of a new voice for main character, Michael Ford, was a huge mistake. The voice of Duke Nukem is a TERRIBLE fit for the character, the setting, and everything else that makes the game not Duke Nukem. Secondly, I've encountered a handful of bugs. The game allows patching, and I intend on writing High Voltage Software an e-mail describing the problems so that hopefully we may see an update soon. Note that none of these bugs are present in the single player or on-line multiplayer modes, but are restricted to the off-line Invasion mode. (At least, this is the only place I've encountered any.) Invasion is tons of fun though, certainly enough so not to be spoiled by inactive AI on one particular enemy type, occasionally scratchy sound when certain Drudge weapons are fired, or the two game freezes I've had.
Regarding the graphics, HVS have really outdone themselves. Unlike its predecessor, the game is not just a technical powerhouse, it now comes with great art design too! The technology powering the visuals remains mega impressive though. The Wii's TEVs are used to great effect to duplicate in appearance just about every shader you've ever seen employed on 360/Ps3. The end result is that Conduit 2 really does look like a HD game displayed in SD. Environments are much richer than in the first game and even the familiar character models have been rebuilt with more graphical oomph.
Conduit 2 hasn't quite overtaken Goldeneye as my favourite on-line shooter on Wii (yet). But it does make for a refreshing change of pace from Goldeneye and most other current gen on-line first person shooters. You create a profile and upgrade your character in a persistant manner as you score more credits. What is surprising though is that all gameplay modes are completely integrated and make use of the same persistant profile. What this means is that you earn credits which can be used towards improving your character regardless of whether you are playing on-line competitively or going through the off-line story campaign. This is not something you see first person shooters do too often, and it really is surprisingly well-balanced here. (Overall, Killzone 2 still has my favourite upgrade tree this gen, but I really love what HVS have managed to do with Conduit 2.)
This post is meant to convey my first impressions, so to speak. I'm impressed. And I wish High Voltage Software would get on with it and give us The Grinder on Wii as it was originally conceived. I feel the developer is now at a point where they've reached a certain maturity with regards to game design, art and engine tech that they can continue the upwards trend set by The Conduit and Conduit 2 and deliver consecutive knockout experiences on Wii. And if we get no The Grinder on Wii this gen, then I can't wait to see what they cook up for Wii U (that isn't based on a movie license).
