Alan v2 is very obsolete. It might work for you but I strongly advice you to migrate to Alan v3. If you are starting from scratch with a new game, there is no choice.
If you want to carry some work with you there is a guide for conversion and a tool (in the SDK:s) to do the bulk work.
Here are some material on Alan v2
Again, Alan v2 is obsolete! Thank you for upgrading!
