OpenBSD is built using gcc 4.2, which is getting old by now.
While being old isn't an indication of being bad or wrong, is there any concrete plan
to either upgrade the base compiler, replace it with clang or some other compiler ?

It's quite simple, there is a vast overproduction of games.
People will only buy so many games, and when there's just too many games, eventually some of the producers will have to throw in the towel.

Which is good for the ones that survives, as they have a greater chance of turning a profit again.

That's assuming those small games would make a profit.
Do you have any backup that such small games would sell well enough to turn a profit. (Other than "I like small fun games, so they must sell well !")
