Upgradable Factories v1.0.0.0

Description

Upgrade your production facilities! With this mod you will be able to increase your production speeds and storages, so you no longer need to place multiple productions.
Features :
- Production chains now have levels that you can increase.
- Upgrading a factory will cost you slightly more each level than buying a new building.
- Upgrading cost is vastly compensated by the gain in production speed.
- More production speed means more storage space.
- Because you don't have to build a new facility, you save on production costs.
- Factory value is increased when upgrading, so you can claim your investment back when selling a facility.

Note that there is no maximum level, only your money will limit you!
This mod does not yet support multiplayer.
