Nintendo have a way of branching out their video game franchises in new and surprising directions, and 1993‘s Mario & Wario is a good example of that.
The game is basically a ‘protection’ game, with you playing a fairy called Wanda who must protect Mario (and other characters) as they wander blindly around the landscape, looking for the exit. They wander blindly because each one has either a bucket, a pipe, or some other such object, on their head obscuring their view. So they cannot see where they are going and Wanda must create platforms under them (when there are gaps) and also keep them away from meanies and traps.
When you pass the first few levels, and really start getting into it, you’ll probably realise what an excellent game Mario & Wario is. It lacks none of the Nintendo slickness and playability that they are known for.
The downside is that Mario & Wario requires the Nintendo Mouse Accessory to play, although that’s not a problem with most emulators (because most will emulate the mouse accessory fine). With mouse enabled (and working correctly) it makes Mario & Wario a blindingly fast game to play, reaction-wise, and elevates it above the norm.
