Actually, I think it was a tad bit more than 8 months. It took them 10 months to make RL... That is really impressive.
After seeing Metroid form Retro, I am eagerly waiting Factor 5's next game. Metroid looks fantastic, and I can only think that since it will be released some time earlier than Factor 5's new offering, Factor 5's new gme will be one step ahead not only in the visual department, but also technically.
Though the proof is in the pudding (which hasnt been served yet
), I do think that technically and graphically, Factor 5's new game will be hovering around the same level as Halo 2.
But nothing can be proved until we see some footage of the new game.
