kB:TL/AP is more in comparsion with HOMM series(all versions)
in HOMM u don't have real time and EVERYTHING IS TURN based) but with almost same units as in homm
disciples
is like the same wise
however
disciples 1 and 2 had limited space
only 6 units per stack(no huge quantities)
heroes could get equipment and potions)
but that's it
in disciples 3 however
they improved the battle systems
so unit could walk like in the homm 5/expansion series
(however for further ingame knowlegde i have no clue)
but disciples was a great game

worth a try anyway
