So, I thought it might be good for us to share recommendations when we discover something awesome... you know... for inspiration and what-not...
For example, I just discovered Biomechanical Toy (in mame). A game I completely missed the first time round. I had never heard of it before, or ever seen it in an arcade. It's like Metal Slug met Mario on acid:

It is fantastic in it's weirdness and surprisingly varied for a platform shmup.
I'll confess, I don't like the Metal Slug series as much as other people. Some consider it to be a Neo Geo top 10 but I find them all to be a little tedious. The games just keep throwing the same two or three baddies at you with little variation. And, each sequel is the same as the one before. Biomechanical toy has more variation in the first two levels than the entire MS series.
Don't get me wrong, the Neo Geo has some great shmups. It just makes me sad to see "top 10 lists" with Metal Slug and no Viewpoint or Shock Troopers 2 (my two favorite Neo Geo Shmups).
So... what are you guys playing this weekend?
