I've been saying for the last couple of years that I hoped, and expected, that many old faces would come out of the woodwork. This is just the start IMO - I'm really more blown away every time I mess with the beta, and that's just with the "standard" MA game, with none of the potential new tricks HTC may have up their sleeve in terms of gameplay mechanics. Based on just what the beta is now, there is enough merit there IMO to bring back some serious numbers.
I've ran into my old CO Rude a few times, we've shot each other down a few times as well, one of the great players/CO, Toad as well - I learned a lot with them in the early years in 13TAS, it was a fantastically ran squad, I never logged on at night without having piles of wingman back then.
Mitsu coming back would be a huge plus for this game, considering how powerful the new sound stuff is with AH3, just imagine the sound packs he could crank out now, as his were very popular and well done back in the day, plus he was a great pilot to be around.
