pimpmonkey2382.313: Hell yes and I'd try to get them all.
Grargar: Not on GOG, but Humble Store has a 50% discount on an
Atari Collection (DRM-Free). I seriously want it and I'm so buying it come Monday.
I believe I got that collection on GameFly a bit back. The launcher worked, but on my Vista it wouldn't launch any game, had to launch them manually. Apart from the 10 or so arcade games, the rest are roms for an atari 2600 emulator. They did quite well with the emulator having access to manual and such though.
I'd like more arcade collections here really. Port or just emulated. There aren't too many PC compilations as it is. My collection of arcade games is Capcom Classic Collection 1 +2 (ps2), Midway Arcade Treasures 1+2+3 (PS2), Metal Slug Anthology (PS2), SNK Arcade hits (PS2), Samurai Shodown anthology (Wii), IREM Arcade hits (PC, DotEMU), Taito Legends 1+2 (PC, the 2nd collection used Starforce for copy protection, but t'was just for the frontend, the files could be directly used with Mame)
I'd love to see a good Data-East compilation. Apparently one was released for the Wii, but it doesn't seem Amazon has heard of it.
