Copying here:
Slayer, if that's true grab DCS World and join us sometime. There are modules to fly additional aircraft but DCS World is free and comes with the Su-25T which is a very capable aircraft. Any maps I make (which is pretty much all we fly these days) include slots for it since we do like to fly it sometimes. It has a wide range of Laser, TV, and anti-radiation Guided Missles, along with plenty of bombs and rockets, and can carry a large compliment in one go, so it is always good fun to fly.

Modules available:
A-10C
Ka-50
P-51D
Flaming Cliffs 3 (includes A-10A, Su-25, F-15C, MiG-29A, MiG-29S, Su-27, Su-33 though they are modeled at lower fidelity than the others)
Combined Arms (allows for control of ground units save Infantry/MANPADS, ships, and multi-vehicle SAMS, and maybe some others)
The Su-25T is somewhere between the A-10C/Ka-50 and FC3 aircraft in terms of modeling. Engine/System startup and weapon deployment is easier, but it does use the advanced flight model.
But you can basically decide if you like it before buying anything.
