I'm already keenly brainstorming in anticipation of the GECK release, and i'd like to hear about the best interiors that you revisit to enjoy combat. I'm an architect and level designer at heart, and the first thing i'll be doing is making underground interiors for combat, primarily in the glowing sea due to the availability of space there. I feel like an extra handful of tough and extensive interiors would really add to the population and density of challenging enemies in the game.
One of my aims is to achieve an interior with scale and longevity that could rival the dungeon in Oblivion Mehrunes Dagon DLC. Being underground for several hours of gameplay, faced with challenges that force the tough decision of continuing on or retreating to re-equip.
There are a lot of lovely new assets to work with for interiors. I'd love to hear what some of your favorite are, as well as any scenarios you'd love to see, like having different factions fighting each other in the process of you moving through.
check out the last thing i was working on for NV, it should give you a good idea of what things i make;
