Well I am planning several games, but unlike heyufool1 I have very little time on my hands at the moment because I am in college taking 18 credits. (Mostly math and engineering) My plan for these is (when they are done) make them free but give people the option to donate which will give them some special badge or item (depending on the type of game) that would Identify them as a donator and give some idea of how much they actually donated.
Now I am in college so I'm not too concerned about making a living off the games. So, I want to have them 100% free yet still make working on them worth my time. If you want to make a living off it TF2's strategy is quite effective.
But probably the most important thing is getting people to play your game. So I would simply focus on putting it in a place where people will find it if they go looking for a free game to play.
So, ya there are a lot of sites out there that host information on games like this and you'll want to get on as many as possible.
Oh ya, and there are a lot of youtubers with a good following that would like to present a game like yours, so you could send some one like that a message about it.

unfortunately, no. some people just seem to think that nothing new needs to be made and that nothing needs to be changed.
