Personally I don't see any problem with charging money for a game. There's quite the cottage industry for various systems.
Now I have seen some utterly optimistic things sold when better things are given away free, and also some fairly idiotic nonsense, but still; I can't imagine the sales for any old system are enough of an income to warrant going to AAA production values. You got more chance trying to score micropayments on iOS/android or whatever.
But who knows, maybe someone is working on an amazing title right now but keeping secret till it's done
