The one other issue I can think of relating to the pricing of games is the new prevalence of bundle games. When someone can pick up a large number of games for around $5 it makes people question whether it's worth spending $5 on a single game. Once you get around $10 it makes it an even harder suggestion. It's true that a lot of bundles are rehashes of games that have already been offered and people who have been buying them for awhile might only gain 1 or 2 new games from them, but that's still a very cheap price tag. When you are trying to compete for someone's wallet and they compare your game at $10 or two bundles that are out at the same time it requires that your game have something that will really drive them in. "Indie" games like Don't Starve, Hotline Miami, and others have managed this fairly easily due to great word of mouth about their unique gameplay. Unless you can really get people talking about the game though it's hard to get people to part $10 for what they may see as "just another indie game". The other issue is the one you've talked about, investing in any multiplayer game that you don't know has a huge following can be very sketchy. If you can never find anyone to play with it's basically a wasted purchase.
