Should you get sonic generations for the PC

It really depends on what you're used to. I personally beat it on PC, but it can be difficult to pull off tricky jumps without an analog stick. The PC version also has nearly no control translation at all, drifting is controlled with the 1 and 3 keys (what?), and the characters will all refer to your controls as their xbox counterparts. It also is just a tiny bit unstable on PC, and can crash once in a blue moon, but you can also change graphics settings to suit your PC.

If you're talking about the game itself, I would definitely recommend it. It's pretty, it's fast, and you'll have tons of fun. Wait for it to go on sale to get the most out of your money though.
