The same reason they keep making those awful sports games.

Castlevania: Symphony of the Night. I don't get why XBox Live already has it but PSN doesn't.

RPG's in general. Bayonetta lured me over to the dark side of Action/Adventuring earlier this year though.

I actually disliked RE's move-like-a-tank gameplay. RE5 was a breath of fresh air.

The games have their differences and will cater to different markets.

Since it was first released for Playstation, Res Evil has been a genre defining series. But I feel that not enough has been done with the games. I mean how different is the first game from RE4? It's basically see zombie - blast zombie. And you occasionally fight a boss. I can see how this style of gaming appeals to some people but I only play it as a filler game between other games.

I'd much prefer games that put the horror back into survival horror. Games like Project Zero, Forbidden Siren and yes Silent Hill.
