Just give me the information I need to make a decision please, and make it easier for me to make the decision.-- JesusHChrist, Jul 16 2013 I'm sure it's been done, many times.
The main problem is most casual gamers like their eye-candy - perhaps to the extent of equating graphics with quality - so minimallist games generally don't get popular.-- Loris, Jul 16 2013 Maybe locking the door at the base of the tower would be a good first step?-- not_morrison_rm, Jul 16 2013 The most minimal would be a tower defense game completely in the mind.
