I assume if you have some games registered on Steam (Windows), when you install Steam on your Mac, you'll be able to log into Steam as you always do and download the games that will be able to run on your Mac?
EDIT: I'll take a moment to answer my own question. This from
Wired Magazine:
* If players already own the PC versions of Valve games, they’ll get Mac versions at no extra charge through a feature called Steam Play.
* By using the Steam Cloud feature that the company introduced in 2008, players can save in-progress games online, then call up those saved games no matter which version they’re playing. If you’re playing Half-Life 2 on your home PC but then head out on the road with your MacBook, you can continue your game-in-progress.
I noticed in Valve's press release, they said "Half Life series". I assume this would include the original HL. The single greatest benefit of Steam on Mac is being able to play the Half Life series natively on your Mac. I consider HL to be the greatest solo FPS series in computer gaming history. At the Black Mesa Research Facility you are Gordon Freeman, a scientist who is involved with accidetnly tearing a rip in time/space allowing a bunch of aliens to pile in. The goal becomes to escape from Black Mesa by duct, sewer, tunnel, through the bowels of the facility. If you've not been exposed to it, I'd suggest starting with the original which although is a bit dated in appearance, is still a very playable game. And HL2 stands up just as well.
On the Windows side, the last game I installed in Steam was the original Half Life that came out when Windows was Window95/98. I discovered that I could not get it to run in XP so I registered my serial number and discovered my serial number had been hacked, apparently by one of those key generator programs. To get around this, I had to write my serial number on my original CD and then fax a cop of this to Valve. It took a couple of days to sort this out, but in the end I could play the original Half Life again! Now maybe I'll be playing it in OSX.
Two other outstanding coop titles are Left For Dead and Borderlands. Very fun games. I assume the coop feature is available through Steam?
BTW I'm still keeping my Windows partition for now.
