Actually, you can write your own roguelike game with "psionics" pretty easily. All you have to do is take a roguelike game you like, maybe nethack, and do a search and replace on words in the source code related to "magic" and "spells." It may help avoid trouble if you can restrict the find and replace to string literals, but if you don't know what that is, it'll probably work anyway.
Now if you really need a sci-fi setting, which isn't at all what "psionics" suggests or implies, you've got more work ahead of you. The first thing you need to do is fix item and monster names. For example:
"saber" --> "light saber"
"bow" --> "raygun"
"X arrows" --> "energy module with X charges"
"orc" --> "space orc"
And of course "magic wand" --> "psionic wand."
Now just alter the intro text, if any, to reflect your new, immersive science fiction game setting. Happy hacking!
