Cause those games still allow full freedom of movement within their environment. Robotron and Bezerk allow you to play, move through and reach every single inch of the screen, as do Space War and Sub Terrania. Contra doesn't. If there isn't a platform there, you can't reach it.Alpolio wrote:Why is gravity a factor? You're not flying in Robotron or Berzerk. And lets not forget that the very first shmup, Space War, used gravity. There was a star in the center that's constantly pulling you in. And then there's Gravitar. And a really cool Genesis shmup called "Sub Terrania" that used some serious gravity.Sly Cherry Chunks wrote:I would say "gravity" is what separates shmups from run n guns - and Robotron from Contra.
Also, I would say that scrolling backgrounds are only a relevent gameplay element where scenery is involved - for the player to crash into and stuff. Clearly, not all shmups have this kind of scenery.
Going by the logic that a shmup is defined by a scrolling background, I could actually stop DDP from being a shmup by loading it up in Raine and turning the background layer off.
All of those are still shmups despite their use of gravity. Why should it be a deciding factor with Contra?
Only logical follow on from Robotron is, as BF already pointed out, Smash TV. Which isn't half the game Robotron is unfortunately.
