I been playing the 2 games for a while and they are one of the "better" tycoon games out there, (yeah I know geeogree don't agree with me, so if you are geeogree and want to say something bad then DON'T post, unless it is for modding reasons).
I will upload some pictures of a park I made shortly after I upload them, it has an Ice land, a Mars area and a hot mini-desert, but overall the land is filled with normal areas.
Here is the place to share some of your parks, or get help,tips or share custom made Scenarios.
P.S : Roller coaster tycoon 3 thread coming soon, right now I am making a Sonic theme park in sandbox there, I am only building greenhill zone
.
EDIT: Basic overview of the park (before the zones) :
(2 game years later)
Basic overview of the park (with the zones) :
Close up at the mini desert :
Close up on the mars area :
Close up at the area near the gate :
Close up on the ICE land:
Close up at the "Grand bridge" (there are shops and toilets on your long walk here, is just none is at this part of the bridge, which is close to the other end) :
And the best part ? I did this whole park without the use of cheats,trainers or other things that can make the game "unfair".
