Despite my previous joke thread, I have had ideas for CRPG, such as a Conquest gameplay-style map. I can imagine a large open castle based map with several key locations inside and outside the walls. I can imagine 2 sides rush in to capture key areas. Some fighters will have to hang back and defend the area. The camp where the players start will feature a limited number of defensive structures such as small wooden walls, horse-traps, etc. Something to almost entrench an area so the team can keep one position and hold it while others go out and fight for new areas.
Areas within the castle or location could include a merchant district, stables, tavern, the keep, etc.
My main idea for this came from some MMOs I used to play. Despite my hatred for WoW's PVP, I did enjoy a few of its capture-defend and hold style encounters.
I could see where troops would head back out of the castle, or area to their camp to replenish their assets. The map will run on a ticket based system. Dying will not cost as much tickets as using a barricade structure nor not as near as much as losing an area.
This style of map will encourage more team-based strategy found in FPS or Mount and Musket!
Just an idea!
