This game has turned into quite a treat for me. Just got done playing actually.
I bought it earlier in the year (around March/Feb) along with PoP, and it kind of got put on the back burner. I had some of the same initial troubles as some who've posted negatively about the game, and only played it in spurts initially.
After finishing PoP I picked the game up more consistently, finishing some of the novice and regular (whatever they're called) difficulty cups, and generally got a better feel for the handling and track layouts. The game again fell out of the rotation as other new games emerged (Soul Calibur 2, ESPN 2K5 etc), but I felt like I had turned the corner by finally graduating from the Blue Falcon to Little Wyvern.
After a long dry spell, I randomly picked this game up a week or 2 ago (not long before this thread emerged if I remember correctly) and I started taking some shots at the previously difficult emerald cup tracks. Low and behold, by maintaining my focus deeper in the track and boosting more strategically, I started to consistently challenge for 1st place, even after the long layover.
Since that day I've completed all the emerald tracks on regular difficulty, and yesterday I finished the last of the expert cup tracks. I've also started experimenting with some custom crafts and unlocked a couple more story mode stages. The game has really drawn me in from my previous "healthy respect" into "near-worship" status.
The only niggles for me are the combat (while I'm sure it can be effective for a skilled vet, the risk/reward ratio just doesn't seem worth it, especially on tracks that you can easily fly off of), and the (admittedly held over from previous games) god-awful character/craft art. I mean some of the ship designs aren't that bad, and the tracks and scenery look absolutely jaw-dropping, but the corny CORNY fucking character designs really kill the uber-cool vibes that I get from much of the rest of the game. I'm sorry but Wip3out staring Bozo the Clown in an aviator jacket just ain't cuttin it. I'm not asking for Solid Snake vs Dante, but could we at least get Akira vs Jak instead of Ultraman vs RuPaul or whatever the fuck? Come on Nintendo!!
Another small nitpick is that, fantastic skill aside, it seems as though only a small percentage of the ships have enough legitimate playability and speed to both be able to handle and still keep pace in the tougher difficulties. I'm sure preference and adaptability have something to do with it, but I mean the under/oversteer on some of these boats is just insane, even at low speeds. I guess with a wide variety, a player should only like a small handful of crafts, but I just have a feeling that if we got 50 people in a room to pick their 3 favs, that 4-5 of the ships would likely hoarde all the votes and 7-9 would get no votes at all. Craft customizing makes for a nice way to alleviate the restraints of the vehicles though..
Anyway, the sum of my gripes does not negate the fact that I love this game. It's weird for a game to so slowly build its way into my increasing favor, but GX just seems to be the game that keeps on giving. With all this talk I hear of the AX tracks, I doubt I'll stop until I've bested the master difficulty cups. I will say of my experience to those who doubt the game, that it really does reveal its greatness more and more with increased play, skill and familiarity (in my case a major turning point was finding a competitive craft that I was comfortable with). It kind of reminds me of Wave Race: Blue Storm in that regard, which I also wrote off prematurely and later learned to love.
Speaking of the AX tracks, I've never played the arcade game. Are the AX tracks just variations on the themes of the current tracks (much how many of the tracks in the different cups are new layouts of the same scenery), or are they entirely new tracks withe different gfx etc?
