While the gameplay sometimes has peaks; it is often too broken and buggy to enjoy.
At first the gameplay seems confusing but once you get past the somewhat steep learning curve it actually isn't all that bad. Which brings me to my next negative point. The difficulty of this game. If you want a game in which you are going to simply cruise through on the lowest difficulty setting then this is an excellent game for you. However if you want a game to challenge you on the hardest difficulty and make you feel satisfied after completing then this most certainly is not a good game for you. Sick is the hardest difficulty in this game and I can tell you.....it should be renamed impossible. I am usually very good at Tony Hawk Games and I found it impossible to finish all the goals on PRO (Medium Difficulty) Let alone sick!
If I could offer you advice I would probably say don't buy this game but if you can get it for under $25 then I would probably buy it. The game isn't terrible but it would certainly be a lie if i said it was good.
