I have set aside a budget for how much I am willing to spend on games per year. That amount is not nearly enough to purchase all the games I am interested in. The price increase is unlikely to remove a game from my wanted list but it may move it down a few slots on my priority list if I believe other games are a better value for my dollars.
I will give an example. I like Infidels and I am interested in Guelphs and Ghibellines. After researching G&G, I believe G&G is a better game than Infidels but after watching Enrico's video review, I think I would get more long-term value for my money by buying a COIN game (especially if my wife wanted to try it). It's not a knock on G&G, I am almost certain I would love the game and I will purchase it if I see it on sale, just that I think I can get another game I may enjoy as much (or maybe even a little less) far more often on the table.
An estimated cost per hour of play analysis is often what I use to rank games for which I don't have a strong preference for one over the other.
A $10 increase per game - an example, I have no clue how much of a price increase Mike is talking about - would also add $40 to pre-order all the games on the new PG/IA bundle. With the games costing $380 before the increase and not taking account the GC discount, there reach a point when I am not so comfortable advancing a few hundred dollars to a company for yet to be published games. Yes, it's almost certain they will see print in 12 - 18 months, but I am risk adverse and I may decide to wait for the games to be published (and 10% more) than being charged a year in advance. After receiving my first bonus countersheet (Morrocans), I know they are no longer a big incentive for me.
