(cont.) Guild wars 2 is another mmo that is worth trying to see if you like the feel of the action combat. You can again play a whole lot free, but you do have to pay if you want the expansion content (which i feel is kind of diabolical to lock mounts behind max level expansion content). I also do not like that you can buy in game currency with real money, and then buy legendary (best in slot) weapons off the trading post with in game currency.

Theres maplestory which is mainly singleplayer, just make sure you make your char on the reboot (non-p2w) servers. Scratches the itch.

Honorable mention to private/classic servers like tera classic which i’ve been meaning to try out. The population being tiny is the most obvious factor but it is nice that the game has been preserved at all for people to play.
