I've been through phases.... My gaming credentials:
Played nearly every NES title, then it was all PC (Win95-98se; From DOOM to MS Puzzle Pack to Rayman to CnC 95 to Diablo 2) until N64 (Tons of 007, SM64, MK64, SSB, CBFD, Mario Party) and PSX (MANY RPGs, some racing like GT2 100% but also some platformers like Spyro or Gex). Then I got a job and was back into PC gaming (far cry 1 era, Barton 2500+ then 3200+) and HALO came around and I got sucked back into consoles for xbox LANs, but primarily PC gaming. Then the girlfriend came along, and I moved out of my parent's house and gaming fell to the side, with the odd gaming binge (WC3's DotA primarily for PC, Metal Gear Solid franchise and Just Cause 2 99.60% on variety of consoles) on the side. Now finally I'm getting back into gaming, and most console games just don't grab me, especially not on xbox. PS3 has a few titles that have been taunting me, but I'm not sure I'll ever get around to playing. Now I've gone and upgraded my HTPC (i5 3570k, GTX 560ti) and Desktop (i5-4670k and GTX 770) and I'm starting to get back into PC gaming, mostly for Diablo 3, DotA2 and various Steam games.
TL;DR - I've played a variety of titles across a variety of platforms.
No point sticking to one platform. There's so much out there, and the control schemes just work better for some games (GAMES, NOT GENRES). Sometimes the experience is just -better- on a different platform. I was 100% Sony and hates xbox, but I was a quick convert, and I've flip-flopped between Nintendo, to Microsoft, to Sony.
