[quote name='mrchainsaw']I can't find an answer anywhere so I'm hoping this thread can help. I have Steam and HL 2 on my laptop, but it doesn't run very well. My family got a new PC that can run it well but I don't know if it's possible to get Steam and redownload HL 2 on it. If that is possible, how to game saves work? Are they tied to my account or to the computer?[/quote]
Oh yea, you can transfer everything to the other computer. One thing you might want to do is create a back-up data disc of HL2 though, since it most likely has self-updated if you auto-log onto steam when you boot up your comp.
Just go to your games through steam, right-click on HL2 and select backup game files. If you have any other games you'd want to back-up you can select them there and I believe it also gives you an option for splittin up the files so you can burn them onto cd's/dvd's then install them later on after you setup steam on the other computer. Just use your same log-in info and your set.
As for your save files, follow the Directories like this: Drive you installed Steam on > Program Files > Steam > SteamApps > Your e-mail log-in > half-life 2 > hl2 > SAVE
Copy all those files to the other save folder on the other computer and you should be good.
