I find that companies who are new to a certain type of genre (e.g. sci-fi/fantasy kinda thing) always crap it up.
Take Bethesda and Mad Doc working together for an example. They're good at free roam games, with swords and arrows and stuff. Then they made Legacy. And we all know how that turned out. Conquest wasn't much better. You could barely do any kind of storyline, just blow the enemy up.
Now, Bungie, who made (or make I should say) the Halo games were probably unsure with the first Halo game. It became popular, so they made it again. Twice (personally, I think the second one was the worst). With huge succes. And they're already in the making of another Halo game called Halo:Wars. Not sure when it's out but, it's coming.
I certainly hope tha Cryptic know what they're doing.
