The cheapest Trine has been is pay-whatever-you-want, since it was in a humble bundle.My problem is Trine was $0.99 during the xmas sale, and I fully expect Trine2 to follow suit.
I have a backlog of games, and I can wait.
With $0.99 holiday sales and $0.49 tablet/phone games, gaming companies are shaping my perception of what's acceptable to pay for a game.
Even a great game.
