From the perspective of the reader/viewer, all those things are obviously beyond Earth reality and thus need no further explanation. And in any case stories and games are different things, as I've said many times before.
Show me a game where people perform superhuman feats without implicit or explicit explanation, because it matters there where it doesn't in a story. Like @dave2008 said, this is a question of game terms. Continuing to bring up stories does nothing to prove your point to me.
Okay, hmm, this will be hard.. let's start with... Dungeons and Dragons.
Okay, Okay, I know that's a low bar. What about Savage Worlds: Deadlands? Cold Steel Wardens is good. Sentinel Comics the Role-playing game. OVA. Maid. I guess technically the system I made for God's road would count, but it isn't a published system.
Is that enough? Or do none of those count because of reasons?
