I KNOW that stablishing a list is too personal and too bias. But forget the little buttons.
This is the way I will do it and I hope that many will follow, and maybe a new thread:
My favorite scenarios:
1) Age of Steam (I-V)
2) South East USA
3) Dry Lake
4) Orient Express (and it's upgrades)
5) 5 Lakes Tycooning
This way, after people answers, a consensus about it could be compiled.
What you think?
