whats the difference between FS 15 and FS 17

[dougb1990]

I was wondering does the 15 version have all the crops and animals the 17 version has.and is there anything different from the two.

Here are just some new features:
- FS17 has a better hardware usage
- FS17 has more vehicles/equipment
- FS17 has sunflowers and soybeans as new fruits
- FS17 has pigs as new animals
- FS17 has a new price/economy calculation
- FS17 has a new physics "engine"
- FS17 has partlly mod support for consoles
- FS17 has a new fieldwork system
- FS17 has an integrated music player

Fs15 has 6 crops, wheat, barley, canola, corn, potatoes and sugar beet. Chickens, sheep and dairy cows but no breeding of animals.
There are 2 different maps in the base game and, if you're on PC, hundreds of mod maps to choose from, many of which have extra crops/animals built in.
The missions are different, with transport, mowing and delivery of crops to sell points, but no field missions.
The in game AI is not as competent, but autocombine and courseplay work well.
For consoles, 17 offers much more but on PC, I would say 15 still has the edge, although modders are working to address that.
