Sparrowhawk, have you played Guild Wars 2 yet? I'm having an absolute blast in it, since the player base is a lot more friendly and helpful that Diablo 3 (which I also played a lot of) and WoW. There is SO much to do in that game - PvE, PvP, World versus World, dungeons...the list goes on. I can see myself playing it for years to come.
My favourite genres are MMOs and RPGs, but I started out as a console gamer with the N64 and PlayStation, with mostly JRPGs. I've got really fond childhood memories of the Final Fantasy series, Zelda, and an obscure JRPG called Jade Cocoon. I played a lot of Oddworld and Command and Conquer Red Alert & Tiberian Sun on the PC as a kid, too, but now that my boyfriend and I have Macs, the choices are a bit more limited, even if we've Bootcamped them. The graphics card on Macs just can't compete with PC.
We've also got a PS3 and a Wii at home (we're playing Assassin's Creed 3, Skyrim, Darksiders 2, Dark Souls, El Shaddai and Mass Effect 3 at the mo, and since I'm a fan of the Hitman games, we may spring for the latest one), but neither of us care much for the Xbox. As stupid as it may sound, I really hate the design of the controller because it's simply too large for my small hands! But back to the PS3, the most impressive game I've played recently is Journey, a PSN download game. If you haven't tried it yet, please do, it's only a few hours long, but an incredible few hours it is.
