Sacrifice, Battlezone 2 and Dungeon Keeper might be up your alley.
They are fairly old games now though which might put you off, but I thoroughly enjoyed both of them on PC.
Essentially they are first-person RTS games. Battlezone you run around in 3D, take control of vehicles and buildings, build a base, gather resources and take out the enemy.

Sacrifice... You're a wizard that runs around collecting souls to summon an army and build structures, you can cast spells that deform the terrain.

Dungeon Keeper, love this game. You're a "Dungeon lord", full of black humor. You build a dungeon, trap heroes, mine resources and destroy your enemies.
However... You also get a "Possession" spell to enter into a first-person perspective on any of your units.

Now, I know they don't have RPG elements, just thought you might find them interesting as-well as they are games known for mixing elements from various genres.
Then you have Evolva... You're a creature that runs around, killing, gathering DNA' and stuff to "evolve". It's 3rd person, I don't remember there being a story to it. But you do need to use strategy to build your character to fit the environment and enemies.
