The movie is both a prequel to the first game, and a sequel to it in a way (kinda like how Resident Evil 3 was a prequel and a sequel to Resident Evil 2 [before Jill got infected, before Resident Evil 2, after getting infected after Resident Evil 2]). Everything before the final scene where Alice is standing in a "dead" Raccoon City so to speak is before Resident Evil 1. Afterwards, Resident Evil 2/3.
And I\'ve been around. Just haven\'t had the time to post much here, or anywhere for that matter.
