I have owned the game for about 5 days now. I have spent a good amount of time with it, doing a lot of global events, moving through the single player, doing some exploration stuff. My thoughts are definitely not completely thorough but I feel I have played enough to form a pretty thought out opinion of the game.
When SSX is about Trick It events on slopes with huge air, logical track progression, and no pits of death, SSX is pretty damn good. The trick system isn't the best in the series by a wide margin but it easy to understand and makes doing crazy things very simple. I find the face that boost is on right trigger a bit annoying however since I'm always holding that and end up doing a lot of the same tweaks since I'm already pressing it into a jump. Going from jump to jump doing huge tricks is still fun and love being able to pull off a full combo and seeing the score sky rocket.
That's the main problem with SSX... it's not all about doing tricks. Now even saying that - when it is about doing tricks sometimes it stumbles as well. So many of these tracks are completely illogical in their design and it seems that they are setup to frustrate rather than push you towards huge air. So many of the tracks on the bigger slopes involve jumps or ramps that lead to nowhere or straight into pits of death. This is ridiculous. The game is setup in a way so you can "trick off of any terrain" yet when you try to do this you're blocked so often. The latter slopes are so non-trick focused they are worthless to play IMO. When they try to shoe-horn trick it into them it's neither fun or enjoyable.
I think part of what makes this so much of an issue is how the physics and player movement is setup. There's a weird simulation going on in SSX to replicate how a snow-boarder goes down a slope. Obviously it's not realistic necessarily but what it does is create so many situation where you are trying to do a trick off a ramp and end up veering off to the side and sliding off of it. This is mainly due to the fact that winding up your jumps pulls your character in the direction you're winding. I really can't understand the reason for this - it completely defeats the purpose of winding up jumps. The game literally tells you "the longer you wind up a jump the fast you will spin" -- when you attempt this you realize that you've completely went off your mark and missed the jump. Duhhhhh??? On top of this, the game is so fast going down the slopes that any course correction is near impossible.
So you've fucked up a jump. No big deal right? They included a re-wind into the game. But here's the rub: rewind negates your combo! Not only does it negate it but it literally puts you in the negative! So you've basically just boned yourself and there's no reason to proceed. Restarting is the only logical option. Now what is the purpose of rewind again?
Going back to what I started talking about: Trick It is fun. A lot of fun. As long as you are on the few slopes that actually cater to it properly, you're going to have a good time. The rest of the game ranges of middling to flat out not fun. Races are the former - Deadly Descent the latter. Especially wingsuit which is god-awful 90% of the time.
I'm pretty down on SSX most of the time. Sessions typically end with me rage quitting because I've gotten tired of restarting the same events over and over because my character decided to land a half an inch to the left and veered over into a wall and basically did a loop-de-loop, killing my combo and ruining any chance of ranking....
First dud of 2012.
