What is an unpopular game/series you enjoy anyway?
Mine is the Army Men series. Objectively mediocre games at best but the concept of toy soldiers fighting over our yards and rooms has always been cool to me
New Super Mario Bros U. Many people may hate it for being the same as the others NSMB games but it was the first Mario game I played and I very much enjoyed it. I revisit it to collect all the star coins.
The New Super Mario Bros. series is far from the first Mario games I played seeing as I was born in the 80's - but damnit they are all among my favorites. File this in the category of "I had no idea people didn't love these as much as I do" up until only a handful of years ago when I started spending more time on online video game communities.
I'll argue that New Super Mario Bros. wii is my favorite of the bunch, but U is also wonderful!
