While I can win on VH I do not enjoy it. Playing on such level just increases stress for me, not enjoyment or challenge (it's no challenge if you know you can do it, just with more of an effort to get basically the same result). I just want a relaxing, fun campaign and as I'm not a rusher anyway, I'll eventually face nice AI armies, shame the tactical AI is bad at any difficulty level.. so I usually play on H/H so that alliances have at least a chance to work.
