At these prices Ill just buy and keep what i want, without the race of finishing before my subscription finishes or the game being taken out of the service.

18 or 30 it doesn’t matter, promotions end at some point. Also, You are buying a subscription based on a promise. It is worse than pre-ordering. You got 1 or two games you know you will playing, they might suck, you might like it.. after than.. what then.
