An rpg would be great, it would sell, and i would love to see it.
Problem was fox wanted to charge mongoose for the aliens and predaor licenses seperately because mongoose wanted to use stuff form all three continuities, and that shot the deal in the head.
Now, an RPG of AVP would be sweet, but since wizkids have the license for the few miniatures they do, this seems unlikely.
Mongoose wanted to do a space hulk style game for AVP, but it was too expensive considering the scale of the game. I think it was mentioned in a signs and portents article that they would have done it for a large mass battle game (which I think personally would have rocked) but it seems unlikely at this stage.
But I r4eally do qwant and would buy an AVP rpg, just avp. You could get around wanting to use stuff from the alien quadrilogy or predator movies by simply leaving in a large armoury, changing stuff, and of course giving rules to modifiy aliens with a bunch of traits, so you can have different speices that appeared in various movies in your game by doing a bit of work so mongoose do not have to pay a license fee.
I want an AVP rpg.
