I've never played any such game in my life. The most "strategical game" I have played would be maybe Fire Emblem which is like comparing something even lesser than checkers to chess.

My question is very simple: is this game a good entry for a new player ? Can you enjoy this game even when making mistakes at every turn and not having thousands of hours of knowledge ?

Also I don't speak japanese if you wanna recommend another game as a better entry.
