True. But again it's a mobile game and you said it perhaps be a tower defence game? It likely...- Have a boring, repetitive gameplay.
- Or if you don;t want to grind, pay to win.
- Be exclusively Japanese, no western release.
Not all Tower Defense game is boring and repetitive.
13 Sentinels: Aegis Rim for the example.
Its gameplay was amazing and the game got many good scores.
Still from what I read on
Famitsu there is shooting element too in the game, so may be the gameplay is not what I think it is.
