In a traditional RTS, resource gathering is largely automated (players send designated resource gathering units out to harvest materials and bring them back to base, and they do it until either they’re killed or the game is won), and it’s the combat that has to be managed. Conkling decided to invert this model in order to eliminate the need for unit micromanagement. In Corpse Craft, resource gathering is micromanaged through the match-3 game, and new units that are created behave autonomously based on a very simple set of rules.
In other words, players spend resources to create undead creatures but don’t actually control them. There’s no base to manage, and no map to explore; all of the action takes place on a single non-scrolling screen.
According to Conkling, traditional RTS games typically keep combat interesting with a simple unit ecosystem, and battles are most exciting when they’re epic and unpredictable. Corpse Craft maintains that feel through a basic rock, paper, scissors relationship between units, where each unit has an obvious strength and a weakness that can be mitigated by sending the unit onto the battlefield along with other units that offset that weakness.
“Each unit behaves predictably, which is important because they’re not under player control, but when you throw lots of units together into a battle, there are interesting and unpredictable things going on due to the huge variety of interactions between those units,” Conkling said. “Battles are emergent in the sense that there are a few basic rules that drive the combat units, and from that you get chaos, unpredictability and interesting gameplay.”
Web based casual RTS games are a very interesting genre to me because they offer so many opportunities for virtual goods based monetization. We’ve seen several MMOGs make the leap from hardcore client based games to more casual web based games and retain their ability to monetize through virtual goods, and I think RTS is the next category to make that leap. That’s why we invested in Casual Collective last year, which has developed a number of such casual RTS games including Desktop Tower Defence, Flash Element Tower Defence, The Space Game, Minions and Desktop Armarda.
