The last 2 AC titles really feel like Assassin's Creed gimmicks, I'm sorry. Yes there is a lot of content and grinding (which seems to be all the rage nowadays), but it doesn't have the vibe I fell in love with when I first started playing.
Back in the days Assassin's Creed used to have a more serious, mystical and atmospheric tone, almost giving you the feeling that you were actually transported back in time. For me it felt next level. Something I never experienced before in gaming, combined with a story better than most AAA movies as well, but nowadays Assassin's Creed has lost that sense of immersion and has become less serious and far less grounded. The storyline also turned from genius into a joke. I guess it's because different people are in charge now with different life philosophies and creative visions. Well.. at least they brought back Jesper Kyd back into the mix for the soundtrack.
I also really hope we will play as an actual assassin again in the next game, killing off corrupted templars.
