Thanks the both of you for the answers!
When seeking challenge, I prefer multiplayer than solo (I then usually loose -I suck at the RTS parts, like at all RTS's), which I keep for exploring the couple story arcs I didn't discover yet and would like to, though the strategic part tends to somewhat bore me as it is
I did a couple skrimishes vs 3 AIs and it becomes much more interesting.
Well, I guess I'll stick to the Dragon on Earth map then, it may be quite long by itself, though I don't really like this map (tends to be boring because you are over-powerful after a couple turns, imo). Maybe I'll do it giving me a handicap, like waiting 3 or 5 turns before starting expanding? Hm. I'll think on it!
Good to know Larian already considered it. While it saddens me a bit, I understand why they prefered it the way it is -and well, it's their game after all!
