Great plan, needs work
The graphics and animation 6/10
the colors 7/10
the ability to easily mouse around and select items 3/10, constant miss clicks and drags, super annoying.
Have to teach yourself the game, not only what it wants and how to use things but also how it rates things. I have a friend who is a structural engineer and he played it, found it fun, but got annoyed that often bridges would have joints fail and there was absoulutley no way to fix it. If the game says the bridge isnt perfect you have NO WAY TO make it perfect, try and try and try all sorts of ideas and you will often still get 2-10 broken joints.
Not very user friendly, would have been awesome in the late 90's but by todays standards its just ok. a good time waster, but plan to get frustrated.
