Klumpen0815: Another thing I forgot after seeing the previous post:
- Having the option to play non-humans like an animal, an alien, a being from another dimension, a mutated result of some experiment, a zombie/revenant/undead, etc...
I rarely play a human if I don't have to.
dtgreene: It's especially nice if said non-humans play by different rules, making the gameplay experience different.
It's one of the things I like about SaGa 1 and 2 and SaGa Frontier. (SaGa 2 DS with 2 Robots and 2 Monsters was a fun playthrough that didn't require much in the way of what some people call "grinding".)
You should really check out
Notrium if you don't already have.
It's an old but nicely done freeware game from the maker of
Driftmoon and I've finished an older version a couple of times.
By now you can choose a human, an android, an alien, a psionic and it changes the gameplay significantly since food, warmth, energy etc... are core elements of the gameplay.
