im assuming you want one that doesn't install?
Offensive Combat. First person shooter as well. needs a good card. Very fun, I still play it sometimes. Bad developers. Laggy when Chinese are on.
Drakensang online. Not necessarily F2P or Pay2Win. Its Free but you basically have to use your credit card for buying everything, including pots. Its one of those could-have-been games. Great PvP.
BeGone. This one is first person shooter/TPS, but might need a decent card, processor. Laggy.
Realm of the mad God. Simple 8bit mmorpg game with really bad developers. People have lots of fun with this game. Theres a subsection in d2jsp for it.
Crystal Saga. Starts out as f2p, then becomes pay a few thousand to be good. Also a could-have-been game. Also old.
Those are the ones I've tried. I put them in rank of how much I enjoyed them. Theres a lot of top down "diablo" like mmos, or so they are advertised. They all suck. If you see one, just skip it, trust me.
