In line with what some others in this thread have said, Heavy Rain may well be a rental for me too. Especially if it isn't a long game.
This isn't a comment on the game's likely quality at all, I think I'll love it. But the sheer cost of gaming this year in terms of time and money means cuts must be made somewhere, and I am starting with new I.P., not established franchises I know I will love.
That not withstanding, I will be getting my hands on ME2 as a purchase, and Conviction and Heavy Rain as rentals at least.
