Russian Front?
TBH, I'm disinterested in ANY European Theater sim. Because that's pretty much all ANYONE makes. The Pacific Fighters expansion for Il-2 was just an afterthought (no really. On a forum thread I was participating in, Oleg outright SAID they didn't give a crap about the PTO, which is why it was such a half-assed POS, and why they were so concerned about adding drawing board-only German and Russian superplanes than good flight models for the PTO aircraft. Or, y'know, late-war American aircraft like the F4U-4).
How many times can you make the latest, greatest, high-fidelity flight sim centered around Luftwaffe vs. the World before they all start to blur together?
The last GOOD dedicated PTO sim was 1942: Pacific Air War (technically PF WAS a standalone sim, too, but it's only real value is to have it as part of the combined Il-2 package).
Frankly, I'm burned out. Regardless of their business model, I'll pass until someone decides to make a worthy successor to Aces of the Pacific.
