Well....yes and no.

That's not really an answer is it, hahaha.
I got it for 360.1. I am way more comfortable sitting in my reclining arm chair playing with a controller. My cat is also happier and has a choice of who's lap to sit on

2. I get to play on our big LCD tv. Also has better sound than my laptop.
3. My laptop may run it, but it would be at lowest specs and still probably jerky.
4. 360 won't have as good graphics as a top end computer.
My regret is really only centred on the fact that
I won't be able to use mods. This makes me sad. I want a carryable camp set up for my wilderness adventures. I want saddlebags and horse call to make a horse actually worthwhile and useful. And whatever cool things people make.
But oh well. By the time I can afford to buy a new computer, there'll probably be DLC and GOTY versions etc. And I wanted to play it now. But again, playing on pc may create control-suffering, and possibly not a giant screen
So really....no I am not suffering platform regret.
