Yah, my english is not good so sorry u...
Because G have played even TearRing Saga but don't know Tirnanog used what engine/software to make TRS?
TRS is very very wonderful (my rate ^^ TRS is better than Berwich Saga)
PS: if SRPG allow char can move with style hexagon grid as Berwich (but when end turn can select one of six directs to defend) is bessst...
That will make game Strategy Turn-base become full strategy. I hope about it everyday I can say...
This is only my idea DEMO (still update)
