Now I don't mean to belittle what you've achieved so far, I think there is a good chance you will host a complete session, however I will say if you were truly going to 1-up what I do, you'd offer medals(my payed component).
Seriously? Just stop, please. For your sake. I made this not to one-up you, but to make a point to you about paywalls. You got a single (maybe two) people wanting to play with the paywall. I have managed to get many, many more people by simply taking your game and removing the paywall, as you gave me permission to do, so don't go screaming plagiarism or copyright to me.
If this game DOES take off and you end up getting 100 people wanting to play each round, THAT's when you can make OPTIONAL donations a thing. Or with that many people wanting to play a game you made, contact a programmer and they'd be more than happy to code the game for you (Sometimes for a price, sometimes not)
EDIT: And by the way, I don't think anybody wants to pay $5 for a forum game. On steam you can get many many FULL GAMES for less than that. If I had any money, I would want to buy a full game rather than a metaphysically drawn 'medal' or metaphysical 'Achievements'
TL;DR? Get real.
