Yes. Back in the day, Ubisoft used to produce some really inspiring games; Splinter Cell 1, Prince of Persia Sands of Time, Beyond Good and Evil, Rayman 1 and 2. Nowadays, even their "original" IPs are basically re-skinned sequels.
Not necessarily true.
Ubisoft's biggest problems are that they're perfectionists, and they have a lot riding on them. This is a developer that is basically a cornerstone of the local economy in Quebec - to the point where they've almost become this "too big to fail" operation.
Almost all of their games released in the last five years have been continually remolded and reworked, even after being near-completion.
Splinter Cell: Conviction was going to be about a drifter Sam Fisher investigating his daughter's death for the entire game, coupled with a unique physics system and more involved melee combat. Ubisoft pulled the game for two years, believing it to be too close to Assassin's Creed, and reworked the whole thing. The final product was good, but got a lot of complaints and backlash from long-time fans.
Ghost Recon: Future Soldier had a similar process - it looked completely different in its early press demos, then got pulled for a year while they reworked it. The game came out to a more or less ambivalent response.
Now they're doing the same thing with both Rainbow Six Patriots and this game. I wish they'd make up their damn mind and release games, because all this delaying kills the hype for a lot of people instantly, and it's very difficult (if not impossible) to get that kind of spark back.
Just look at what's happening with the Thief reboot - it's been in development for so long (and has been on pre-order for such a long time) that online gaming stores have been slashing the price by anywhere from 20-50% during sales to move units. For a game that hasn't been released yet.
