Right now one thing I’m not lacking is space, so even (very) large scale battles would be possible (assuming I ever get off my xanax and tryptophan groundsloth ass). I need to take some fearsome United Satanic Apache blöd oath and just approach it like a rabid mo-sheeeeeen!
I agree about the power of terrain and scenery. Another good question is whether or not to go with 15mm terrain with 28mm figures. It varies from the looking like something seen in a fugue state to powerfully realistic.
