Err... Psionics Are Different, but with some house rules:
[House Rules]
IMC, Psionics Are Different, but effects are the same.
So, a psionic Eradicate Invisibility will reveal a magically Invisible guy, but you can't dispel his invisibility with a dispel psionics power.
Likewise, force screen protects you from magic missile (and -- heavy house rules here -- concussion blast), and shield protects you from concussion blast.
Aura alteration can affect any effect with the [Compulsion] descriptor, be it a power or spell. Break enchantment can negate many [Mind-Affecting] powers, and true strike will negate the miss chance granted by concealing amphora.
The only places where "different" really comes into play are:
- Metamagic vs. Metapsionic Rods (and Crystal Capacitors vs. Pearls of Power)
- Spell Turning vs. Reddopsi
- PR vs. SR
- Dispel Magic / Dispel Psionics
Even then, monsters with SR or PR get the other one, albeit at -10, unless they are supposed to be seriously powerful (like Dragons, Elementals and Outsiders, who get both at full strength). Half-Fiends pick which one is strong and which is weak.
[/House Rules]
All in all, I think that were I to do it over, I'd use the "reduced potency" variant, where dispel magic would work on psionic powers, but at -4 (and vice versa).
