Ever make a mistake of buying a game on one platform and not another ?

Have you guys ever made a mistake of buying a game for one platform and not another one you own ? I bought Crysis 3 for my 360 and not my PC, well im an idiot! I admit it, i played each and every Crysis on PC, but wanted to play on my big 60" tv and on the couch, now i really regrett it as im missing out on a lot of eye candy, and its not so pretty on my 60" 3D tv :cry: 

Any one else made some mistakes like that ?

Nope

Nope. I bought the best version of my CoD's, aka the Wii versions.

kinda. i bought mass effect and oblivion for the 360. but i didnt have a PC capable of playing them at the time. however i did get that PC a few months later due to an unexpected bit of cash. dam my lack of ability to predict the future!osan0

Same here! I bought Oblivion on PS3! Then bought it on PC and wished I never bought it on ps3.
