We have two PCs which are suitable for gaming and a PS3 complete with the full Move thing for 2 people.
My GF actually likes playing games more than I do, I think...!
I've always loved RTS games, but in the days before online play. I'm one of those annoying turtle people who sit in the base, build up and build up and like 2-3 hours later, wait for all the resources to run out, thrash everything on the screen with an enormous force...
The original Starcraft was bloody good; starcraft II is also fun. I hate buying a game only to find they've basically decided online play is where it's at - I like a bit of a story line to a game rather than just "ooh, shiny graphics, now let me start FRAGGING!". Before that I spent far too much of my teenage life playing Wing Commander: Privateer (we figured out how to "hack" the save games with a hex editor and gave ourselves lots of money), Dune II (which pretty much started the whole RTS thing), Command and Conquer and then Red Alert. I also spent hundreds of hours playing Sim City 2000 and Transport Tycoon, where I took immense joy in building diagonal rail tracks (which can't be crossed) wherever a competitor was trying to build anything, forcing them out of business and monopolising everything. muhahahaha. You then started pulling in silly money and could do things like create entire map-spanning rail tunnels for several tens of millions at a pop and hardly notice the change in your bank balance. I even went to the extreme of creating an absolutely flat multi-level map so I could tunnel across the map in several directions without needing crossroads.
We spent Valentine's Day the year before last killing zombies together in Resident Evil 5.
I've never really liked RPGs; they tend to be too slow (and the idea of a real world RPG like D&D fills me with instant boredom. Plus, dice hate me).
I also quite like games like Tropico (sim city: dictator edition).
Ahh, the folly of youth
