Lets see here.
Dungeon runners, repetitive horribly, and it's free sure, but unless you pay you don't even get a bank (thats just one of the many things you don't get).
Warrock, it's ok, I did play a lot before it went live, now it's a bit meh, the community of course still is full of idiots, but besides that it's ok, though they changed a lot and it's hard for me to get any where.
Granada Espada (I always call it that, not the sword of the new world). It's Ok, but it's just a game you don't have to actually play to level, all you do is get up a family, and AFK it somewhere and go do something else. It's rare to find someone thats actually there, everyone just AFKs.
2moons..meh it's ok. Though they really didn't put much work into it. When I played, none of the NPC's were in the right spot, and if they were they had a completely different name then they were supposed too. The dungeon run things, are easy for a quick grind, but get repetitive after the first one. I'll just stop there.
kwonho, it's ok i guess..that is if you can actually get in a non laggy round with people that don't whine every time you kill them. The player base is small, and most of the time when you hop in a game, it lags because some people just hop in what ever sector they want.
So, Thumbs down on all games suggested, I of course have no suggestions, because I haven't even found a game I like for a good month or so.
(Well, except warrock, that ones still ok, just i'm not used to the changes they made)
