Definitely Anachronox.

The Infinity engine games were very hard to come by until GOG re-released them.

i second this, i only ever found the "bonus" discs that came with graphics cards back in the day with infinity games at swap meets never full retail...

Realms of the haunting is another it was never released digitally before here plus it's the incredibly rare UK standard edition.. unfortunately thats a bad thing so be sure to install the upgrade patch from the forums here...

When I first joined GOG, Real Myst and Gabriel Knight 1 were both $100.00+ boxed games from Amazon and $50+ WHEN available on Ebay. (even used, they were near those prices, so it wasn't an issue of being collector's items) I think I saw STEAM picked them up as well so they aren't GOG exclusive.

I've actually seen the Apogee games for sale on Impulse, which isn't a great download service, but I ended up with gamestop credit after trading in my 360.

You are correct. I guess they're the only other one.

I didn't see Blood on there though, so that one still might be a GOG exclusive...

Why must gog post my posts in the wrong threads....?

I guess I'll contribute now though, aren't Thief and Thief 2 only on gog?
