So I've been playing this recently...

Back to Assassin's Creed, after first three assassination missions, the game doesn't change anything. Assassinating again, in same towns, just in a different part of it. Same repeatable quests, saving citizens, climbing towers. So I actually saw everything that this game has to offer after 1st assassination quest.

The boss assassinations are (almost) all pretty good, but yeah, the same build up to each one was a boring grind.

I don't think I'm going to finish this, not worth my time. Just gonna check wiki/yt for things and move on to something else. This game is almost tragic.

I still love it - it's the best AC from a historical perspective, and although the Ezio trilogy having so much better gameplay, there's always that part in me that keeps that special feeling for AC1. Not enough to go back to replay it again, though.
If you can find some good saves, you might want to just try the boss missions.
