I vouch for the effectiveness of Licuferoh's idea on all maps not containing holy or bog towers. I'd progress about a fourth throught he game then grind on a few of the earlier maps with that setup until you have supplied yourself with all of the healer and shield upgrades.
Developing this into a MMORPG would be epic. It has great potential, though it doesn't seem to have been worked with all that much yet. Would be glad to see an installment at some point.
Are there storyline differences at all, or mainly just game mechanics and such? either way, I'm not playing mardek 3 til i replay the 1st and 2nd for the millionth time >=)
