lol i have never looked at NWE but i heard people complain about it.
If you have worked with v2 i would suggest redux as a update, when v3 comes out im sure they will do a upgrade fee for redux to v3 but i don't know about v2 => v3 (this is speculation not confirmed no need to reply trolling this i would prefer a pm)
Redux can seem difficult at first but if your confident with v2 then redux will be a breeze compared. Going to a completely different engine maybe slightly more confusing than Redux.
How did you find the template script peter?
