I'd like "helper tools".
So say you are building a lift hill. Place your bottom piece of lift hill, then place you last piece at the top level. Then simply click "fill with lift hill pieces between". Voila, you have a lift hill between the two markers at whatever angle it needs to be.
Same with most of the track, you essentially draw the path you want your coaster to travel. It can still work in "blocks", but the track between is flexible. You could even have flexible inversions.
Likewise, for building paths. I want it to "start here", "finish here", this type. It then generates the path between. It the land is too jagged or steep, it forms the land correctly for you, or automatically adds steps.
And for buildings. A simple system of "standard building, 20 blocks wide, 10 blocks deep, five blocks high - painted in "castle".
You could still modify individual blocks if needed, but it would be nice if the game could create them. You could also do something similar for circular buildings. "Create a round building that occupies a 12x12 block area, six blocks high". Then "create a domed roof that occupies a 13x13 block area" and you put the domed roof on top yourself (with some overlap to look good).
There's so much more as well, but I think "building flexibility" is really for me, the key upgrade they should go for, and it's something both PC's and a modern gaming engine could cope with today.
Sorry for the serious post :roll:
