It's funny, 120+ Steam games and not one problem. I find that astounding considering the OS and NET add-ons required by each game, etc. I must just be lucky - and using XP can't hurt.
^ same - almost....
2 things have cropped up in my time using Steam.
1. GTA IV - no matter what I did, I couldn't get it to run. Contacted Steam...and as quick as their response was, it was totally useless and a "shrug off" - basically contact the developer. It did get sorted by me surfing the net and I think something just "fell" into place and it worked. That took almost 2 weeks. I think in the end it was some old version of a third party piece of software - so it was actually more to do with the crap the dev had included in the game as opposed to anything Steam. Still - it's always nice to know your point of contact for purchasing is your point of contact for support - with Steam it's not so be prepared to surf if you have a problem with a game which does not seem to be Steam related.
2. Recently bought Skyrim and Batman Arkham City and when I was directed back to Steam from the Paypal page, there was an error. The two items showed in my cart and I looked in my library and the games were not there. I rebooted Steam and the same thing...so I contacted Steam. The advice was to restart Steam. In the end, I had my Library set to "Installed Games" - when I set it to "All Games" they were there but showing as not installed (obviously) so I installed them. Those two items stayed in my cart though. In the end I just removed them from my cart.
Two problems in about 100 purchases and hundreds of hours gaming - across platforms (Win XP, then Win 7 64bit). That's not a bad record.
I'm not saying Steam isn't without it's problems and people do not have problems...but I think it's generally painted in a much worse light technically than it really is.
I not a fan of their policy though - still, I take the view that until I come up against it, I'm not fussed with it. When you hear me cry because I've been bitten in the arse with their policy, you can laugh and point to this thread...I won't be offended :-)
I AM the Law!
