I think it’s a valid point that games which have been ported to other consoles should get sequels on those consoles. I can understand why someone would be upset if someone bought a new PC for Halo, only to find out that Halo 2 was never going to come to PC (the option is much more attractive at the moment since the PC version offers improvements over it’s Xbox counterpart). Whilst it might happen, it probably won’t be for a good while knowing Microsoft’s marketing strategy. With Half-Life on PS2, why should PS2 owners miss out on the second part in the story just because the game was originally on PC? It is a PS2 game, and there are people who bought it on the PS2 and expect the sequel for that system. While developers obviously have their reasons for not continuing the game on that platform (the system dying as with Tomb Raider), who can blame fans for being angry at the developers for making them miss out because that developer has decided to no longer support their platform.
