Earth Defense Force 2017. It's a great game that sells on a really basic gimmick; the gimmick of destroying gigantic spiders/ants/things with various weapons. There's something like 53 levels and 5 different difficulty levels (easy, normal, hard, hardest, inferno) to go through. It's eaten about 130 hours of my time but I've done pretty much everything there is to do in this game.
Unfortunately co-op suffers as there's no online, but D3 Publisher said they're making another EDF and it'll have online co-op. If so, I'm buying it day #1. Problem with this game is that it has terribly clunky controls, horrendously massive lag (especially on co-op), and in general all you're doing is rolling around collecting items. Oh and there's grinding. In a shooting game.

What could possibly go wrong? Well uh, nothing, because I loved this game as a kid and I've beaten it a whole bunch of times. The music's catchy, the worlds are colorful, the enemies are neat and as are the bosses. Thing is, this game had some weird inertia which made you crash into enemies if you weren't careful enough, and I guess that put a lot of people off.
I heard the SNES version was inferior, but I've never bothered to play it. I think most of the hate comes from Bubsy 3D, which I played on release, and didn't really care for. 3D was still a foreign concept to me at the time, but I knew the games weren't the same. I honestly don't understand why people dislike the first title though.
So what other bad games do you guys enjoy, regardless of their mediocrity?
