PC. There are muc more tactical games for PC and because of console games always being limited on that controller, you are always limited in your way of controlling, because of the few buttons and the worser aiming, then with keyboard/mouse. (Playing dragon age on console was horror and I did not go on with it. Playing it now on PC is really great.)
As well that typical console genres, are the ones that less likely attract me. So in racing games, sport games, Beat m Ups, action-"RPG"s, Jump and Runs, I am rather uninterested.
My favorites are typical "building/economy"-games as Anno, Settlers, as well as strategy games like Warcraft/Starcraft/ ..., classic RPGs that are about group and ressource management and not about pressing X-X-Y-forward to do this or that swordcombo ^^, as well as adventures, from now and then tactical or sneaky FPS or MMORPGs that are rather rare on consoles, or have far worse controlling with the limited controller capabilities.
And it might sound weird, but I really dislike playing games on gigantic television, because you hardly mention something blinking in the right below corner, if you are focused on something that is one meter away in the left upper corner and so on. I like to see everything detailled at once, in a way, that I can focus on the whole screen all the time and dont need to wander around with my eyes.
Just as I truly love my office chair. Its a real expensive one "chief-chair" that I got for free in my old company, when our company boss bought himself a new one, and wanted to garbage his old one. It really looks like s**t now, but its soooooooooooooooo cozy and big. (Cats and I are still arguing, about whose chair it is. ^^)
