I migrated from European Air War to Aces High. My K/D was usually quite high (8/1 or so on average IIRC). Once I can afford new rudders and throttle I'll be back.
This means that EAWers kick both AHers and WBers arses.
Because AH and WB are so simple and unrealistic compared to EAW.
Seriously, this is a very good idea. Hopefully the good vibe can be kept thorough the duelling and afterwards - and maybe some mutual respect can be built.
As long as you know that ex-EAWers are superior in any flight sim to AHers or WBers. Just ask Ripsnort who tested me on my very first night in AH; I absolutely dominated him. Almost.
