I use Sony Sound Forge Pro 10 for recording and editing, and use an ancient Cakewalk sequencing programme for more complex sound assembly. I have numerous plug-ins for both. Sound origin varies from field recordings, software synthesis, hardware synths & samplers and borrowed samples that have been heavily modified.
All of the sounds are ultimately put into Firelight Technologies FMOD Designer to give the dynamic control and create the events that the game engine calls.
I think Landros uses Sony Vegas, which is essentially Sound Forge Pro + video editing facilities.
