Saurok are the main “lizard” race in the game. There are also Sethrak who are a snake race. As far as I know, those are the only big reptilian races in the game.
That said, a lizardman race is something WoW is very much lacking. It’s one of the reasons I created the Saurok megathread to support them as a playable Horde race. They have a big hurdle to overcome, but it’s not impossible to work them to be playable, considering BfA has tribe of them are working together with other races as pirates.
Since you mentioned specifically wanting a lizard man race, if you’re interested in seeing all the ideas and discussions about playable Saurok and want to help support them, you can find the Saurok megathread here:
As for FF14, there isn’t really a fully playable lizardman race in that game currently. There are Bangaa as a NPC race, who are a race of lizardmen, but I’m not sure what the chances they are in being playable. If they ever did become playable, I’d consider giving FF14 a try.
Anyway, heres hoping we get a playable lizardman race in WoW in the near future!
