Civilization Simulator's top notch feature is the graphics. 3D like, and have rotating maps as well as innovative rendering engine
The controls are good, but I really recommend you read the readme before playing it, so you know what you are doing.
Here comes the only problem of the game: it's slow. But as a BASIC programmer myself, when I say slow, it's REALLY slow, and I must retain myself from flooding this text box at the moment with the word "slow" so this review make it through ticalc.org. [Editor's note: Thanks.] This is very annoying to wait minutes to load maps when you accidentally make the screen scroll when you don't want to.
Memory requirements are reasonable for the type of game it is.
Replay value: 4/10
The game speed take replay value down a lot.
On a real calculator, 7.2/10 on an emulator. The engine still amaze me today though and I think just because of that it deserves it's feature on ticalc.org. I wish something like this was done in assembly, thus, faster speed
