Final Level: Memory 7
Why It Sucked: Talk about a botched reveal. After Memory 7 wrapped up, we wandered around Desmond's sterile crib for 20 minutes before we realized there was writing on the walls. But what does it mean? It's not like you'll ever know, because guess what, the game's over! Come back for the sequel!
How We Would End It: At least if you're going to leave us on a cliffhanger, explain what the shit is going on. Explain that the Animus is screwing with Desmond's perception of reality, or that the abilities of his ancestors are starting to bleed into his DNA. Then let us kick some modern-day Templar ass.
