i know Oxford made everything that came out while Core still existed as a seperate entity. so that includes the good (Alien vs Predator on Jag, Aliens vs Predator on PC, Rogue Trooper) games, the bad games (Judge Dredd) and the inbetweens (Sniper Elite).
anything after that... the only ones i know as a fact are Rogue Warrior being Rebellion Derby, and AvP being Oxford again.
I too was very worried by Rogue Warrior until I found out who it was made by. I think Rebellion have brought their A game this time. AvP was the franchise that made them. That has to get them to try their hardest. It gives them a lot to live up to. As does having to live up to the licensed properties.
If they drop the ball on a new AvP... i think they're basically done as a studio. If they can't motivate themselves to make a great new game given these circumstances, when will they ever?
So far, everything I've seen basically lends me to believe that they've recaptured the magic again. I hope I'm not mistaken. I upgraded my PC to be ready for this game.
edit: yes I know the elephant in the room is the AvP game they made on PSP... but I don't know which studio made it, and any movie tie in like that, that's bound to a shit movie and a hard release date and to be on a portable like that... I don't think it'd be fair to expect such a thing to stand up to the proper games in the series.
