The altitude of the participants is the #1 reason I will not fly in scenarios, man-made restrictions help but do not eliminate the problem, the last BoB scenario is a good example, the British flights routinely flew at 40k and we ended up seeing 109Es even higher.
I'm not asking to fly in a scenario with a pre-arranged outcome (either side winning or losing) but I want it to feel at least a LITTLE realistic with altitudes, combat situation, etc.
The other reason I refuse to fly in scenarios is the lack of participation... if either side gets a large lead in the first 2 frames, you might as well cancel the remaining frames for lack of attendance on the one side. I don't care if my side wins or loses, I normally download music for the period and enjoy it during the scenario for the historical feel. Score is the least important thing to me.
List of importance to me (this would make a good poll question for the scenario site btw).
1. Realistic feel- not a carbon copy, but more than just historic match ups at 40K).
2. Participation- during BoB, I had a different XO every frame and was extremely stressful, more so since I had so many computer problems during that time.
3. Sense of fair play and respect for the other guy- this includes both the boards and the rule settings. Included is a lack of whining and static rule set, unaffected by said whining.
4. Kills- except for when I fly with Guppy in a scenario
, I don't care if I get kills, so long as the group I am flying with has fun.
5. 'Winning' the scenario- for me, taking part in a good scenario FAR outweighs the score factor.
