Ubisoft seems to bring out a new Assassin's Creed title each year and you would think, considering the size of each game, it would have to move mountains to achieve this.
But when you take a step back and look at the series as a whole, not a lotchanges from game to game - with the exception of last year's excellent Brotherhood.
I'm fine with the "if it ain't broke, don't fix it" attitude.
It's a lesson that's been learned by several developers, and Ubisoft has obviously taken this on board.
The latest in the Assassin's Creed series, Revelations, sees more of what we've come to expect, with a few forgettable features thrown in to qualify putting "new" on the box.
Those of us who have come to know and love Assassin's Creed will welcome the chance to play a different storyline and immerse ourselves in the ancient world in which our protagonist resides.
Years after the happenings in Brotherhood, an older and wiser Assassin Ezio is back and seeking knowledge locked away by our old friend Altair.
The search for the keys to this library of knowledge takes Ezio to Constantinople, following the Ottoman Empire overpowering the Byzantine Empire.
The game is as stunning as ever and, as in all the Assassin's Creed games, climbing to the highest point in the city and soaking up the vista is a joy.
Revelations comes across as a gap-filler until Ubisoft can think up something new for the series, but make no mistake, it's a very nice gap-filler indeed.
