Mario + Rabbids is a surprisingly charming and well animated game, held back by samey and drawn out mechanics.
The world building and general story were great, they felt engaging and funny. The cinematics had great animation and really added to the experience.
Gameplay wise however, I felt that even though they made a great decision trying to combine a X-COM style strategy game with the Mario and Rabbids' universes, what it gained in simplifying the formula, it lost in depth of gameplay. Midway through the game I felt bored and sick of using the same guns/strategy and characters to advance through what seemed like should have gone by way faster. It really picks up at the end though, so I was glad to chug along the boring parts.
Overall I thought this is an interesting game, with good presentation, that felt a little long and repetitive.
