Spelunky VS. Trials Evolution Which should I buy

Both a 1200 msp. Both a very hard. Spelunky is randomized which is cool. I just wanted to know what you guys thought was better.

Also: Alias vs. X-Files vs. 24 as my new show to watch on Netflix when I have free time.

Trials has so much user content at this point. Spelunky is great, but I see Trials lasting longer.

Spelunky is free on PC.

EDIT: Apparently there's quite a bit of difference between the PC and Xbox versions. Nevahmind.

TRIALS EVOLUTION

no Doubt, has more tracks replayability

im still playing it to this day since it came out last year.

Go in download some Custom maps and go to town.

Trials

X-Files

Spelunky is randomly generated, so you could say it has more levels than trials.

Both are fantastic, but I'd say Trials just a bit more than Spelunky.
