Well, good game. Sadly, at least IMO, almost no game he did ever got close to Adelaide Inn (only Tenants of Dead got a bit close)
well, do a bit of research on how around 80% of world population is poor. And I'm not saying US or EU poor, I'm saying, survive in a month with 100-200 dolars/euros poor.
So yeah, even if the majority of people have a 64 bit machine like us, it's not everyone. For example, I work in Brazil government, one of the top 10 highest GPD in the world. Its common for government PC here to run Windows 7 for the majority, and a GOOD AMOUNT run on Windows XP, using old crap chips from Intel, like Celeron.
So yes, there's a lot of people who don't have the money for a 64 bit system (or hardware that support it). Let the dudes jerk off in peace ffs.
And get out of your bubble for a bit, will do you good.
