I really don't have a top 5, but here's two that I like from the top of my head:
Glados (Portal 2)
Pagan Min (Farcry 4)
Vaas is overrated.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
