I'm not a big fan of strategy games.
I haven't watched sentais in more than 15 years.

I immediately fell in love with this game.
When you have hundreds of games to play, it's rare that your attention span is long enough to bear trough an entire game.
But I finished it in one go. It's that good. It's cute, it's funny and very very well made.

You make your own team of sentais, fully customizable, down to the actors, colors, and all the catchphrases.
The gameplay is simple, but very solid and you'll have to carefully planned your move because your opponents are ruthless.

Personal recommendation : go straight to the hardest difficulty even if you have very little experience in strategy games, I only had a tiny bit of trouble with medium.
