I just spent about $100 over at GOG. Picked up the Tex Murphy series (got 1+2 free last month during the promotion), Postal 2, 1nsane, all of the Pro Pinball games, all of the MegaRace games, Sanitarium, Obscure, Giants, Manhattan Project, Expendable, and several more titles.
A lot of the ones I mentioned I still have on CD, but IMO, they're worth buying again. GOG deserves the support and I really appreciate what they're doing.
