[@KoL] Thank you for your interest, I'm touched that it's enough for you to consider making time for it.

To answer your question, any real world fighter up to the forth generation is fair game and no one needs to pilot both mecha and fighter, they can specialize. I'll gladly let the Su-37 or other Flanker variants in, I'm just against fifth generation fighters in the beginning since all the fighter jet RP's that have fifth gens in the beginning end up having, out of ten fighters: four F-22's, two F-35's, three flankers and one PAK FA, with any others being F-'teens. The Su-37 is fine though!

For everyone's reference, while I'll set up certain mecha and real fighters as the standard issue, I'll allow you to fly a machine of your choice, so long as it's within the realm of reason and fits the setting. Other mecha, even fictional jets are fine, just describe them well and make sure they're not too obsolete and don't surpass the fourth generation standard (I'll allow so-called generation 4++ though) for fighters.
