One of them surely is available on facebook and kongregate..in fact we are a little late for the cake with fb and other portals somehow already having worked out ways to for players from different sites work together. At least that's the case with Clash of the Dragons - we can only add ourselves as friends from ag level, they can merge lists from the two sites. I didn't check the other games
I think that if we were able to rate them, they would be off the site immediately due to the ratings being 0/10 - 2/10. I have yet to find an MMO that didn't require you paying to play the full game.
