I played it in RPG style on my first run, Womble. Cleared out the spawn spots, activated my hero monuments where I could - and the game was easier, so I missed 2 level ups. And where I could => I even cleared the maps all on my own (Necromancer)
On my 2nd run I made it as strategy - and had far more enemies, so 2 levels more - and a bit strenuous on occasions.

Both styles were fun for me <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
