Not roguelike at all. I know exactly what you're looking for, and no, this game is nothing like it
LonaRPG is an action RPG. It's not a game about numbers, it's about knowing the game mechanics. It has a lot of real-time fights that can get hectic quickly. It also has stealth, by the way
This game is not about subverting numbers. Your DD skills won't help you here
No, I'm not trying to discourage you from playing it. In fact, I highly recommend it because it's just good. It's just that this is definitely not what you're expecting. If you like real RPGs (but more fighting oriented, not talking), this is it. It sometimes reminds me of the OG Fallout games (like 1 and 2) or Gothic. Yeah, Gothic is a good example in a sense that you get fucked at the beginning because you have no idea what to do. But it's nothing like DD. At all
