Firstly, This should be in a seperate forum altogether, wouldnt you agree?
Ok, I'll start by saying that I bought this on ebay for £3 and it was worth every single penny.
The 3d mode itself is worth the purchase, not to mention being able to watch the trains going along the track
The AI is quite bad. Not only does it do the same stupid overly-complex routes as in TTO, they will use full load on the wrong industry, trying to get coal out of a power station (on full load). Not only that but on occasions they will build airports seemingly in the middle of nowhere, and use vehicles when really they should use trains instead (because vehicles are sabotagable in this; anyone remember the level crossing exploit? its in this game too).
I've never seen AI use ships EVER... and theres so little water most of the time that its kind of useless.
As for the vehicles, there are now about twice as many differnet kinds, although most are clones of others with +5MPH/More Expensive.
Although the graphics are a bit blocky, some industries look quite nice, I like the power station quite a bit.
The maps in themselves are small, i'd say they were 96x96 or maybe smaller/bigger. You can only have 3 computer opponents at one time and the max station you can build is 4x5 (or 4x4?).
Because the maps are small, the industries seem to produce a lot less then the TTO counterparts. Also, the economy is officially BROKEN.
By 1970-1980 the economy goes insane, with trains costing millions etc etc. I havent gotten to monorail yet sorry, but I assume it exists.
But yes, it is a fun game and could certainly do with some sprucing up. I think the next OpenTTD game should be a bit like it. (With the 3d Graphics and stuff)
