Just finished the final 4. I probably could've done with a tip for the Young at Heart mission, but I managed it after a few tries. It's nowhere near as difficult as Hell on Wheels & definitely not as stressful. See, the problem with the war machines is that you have to keep restarting the missions & it can take forever to get to the part you're struggling with. Young at Heart doesn't have this problem because it's only 60 seconds each time (if you're going for 100% synch).

Anyway, I've completely 100% synched every game except for 3 & the DLCs (I'm working on 3 & I will purchase the DLC in the future). I consider AC2 & AC1 100% synched because there is no 100%. So even though I've missed killing the Templars & collecting flags in AC1, & finding all the feathers in AC2, I don't feel like it is incomplete.

Have you 100% synched all the AC games, Fairy?
