I love the ability to buy houses in the main residential centres. However, having toured around the wonderful environments that are created in open world games like the Elder Scrolls, I sometimes feel frustrated about the inability to be able to use the natural landscape as a home base as well. Wouldn't it be great if, in future games, you could make camp in the open environment as well as buying town houses? This could take the form of a tent, bedroll and cooking pot and maybe storage for a few items, with a decent safe zone perimeter around the camp. This would mean that when you stumble across those beautiful spots in the game, whether it a plateau looking across a lovely vista, or even on an island in the middle of a lake, you can make that a home camp for as long as you like.
Also, more stables for horses please - I know it's only a game, but I hate leaving my horse outside in the cold when arriving at villages!
