i'll give my impressions as a consumer of games.
my favorite prices that i'll usually buy games at without any problem. 5 usd for a short experience. 10 for a modest one. and 20 for a massive one. and if it's triple A, digitally 40 is okay with me. 60 requires massive hype, and even then it can still be uncomfortable.
notes : i never like it when games go for under 5, always feels like they need more respect for their game. 10 is usually an auto buy if i'm interested enough. 20 requires a bit more research if i really want it.
