How about some simple combos in combat, which work in a rock paper scissors sort of way. So it isn't just tap the attack button until your opponent is dead, but use a mixture of combo A and combo B to beat the enemy, but combo C is useless against this enemy.

For what alternative? 100% success rates?

How about we own our own shop in the game. You put your loot in a chest and it will sell. You can upgrade you shop to hold more inventory and you can hire a guard[s] to protect your wares from thieves.

Sounds good
I'd also like the other merchants to actually move their wares on the map with carriages, boats, handcarts... caravans with guards that can be ambushed, etc. You could ruin a trader's business by attacking and looting their transports regularly, something like Skyrim's now famous "sabotage the local economy".
A traders guild with specific quests (influence games, sabotage, cartels, social ascension) wouldn't hurt either.

OR just be able to hire someone to mind the store.

I've already mentioned the PC needs more money drains like: payroll, taxes, maintainence, extravagant items, whatever, to press having to make/manage money. Basically a world economic system, especially when it comes to things being rare in one area vs. another having appropriate cost varience.

OR, war or whatever causing availability/demand/prices to fluctuate accordingly.

Beyond skyrim.

I wonder, TES3 only features Vvardenfall. Not the mainland Morrowind. Could it be possible that we go to the mainland next?

I see little chance bethesda would pull a blackmarsh or elsweyr simply because gamers wont be interested in playing cats and lizards and seeing them everywhere. Notice the last 3 TES games are all humanoids? I m also not quite sure bethesda is confident to introduce valenwood as the 'moving cities' are quite a chore. Given the fact they butchered winterhold and windhelm out of laziness, i can see Valenwood wont work at all.

So it comes down to Cyrodiil, Mainland morrowind, high rock, hammerfell and summerset isles.

Obviously we wont visit cyrodiil again unless bethesda surprises us. But we didnt visit Mainland morrowind and that is a big place.

A thread of ideas from the Nexus forums. I don't agree with some of the ideas, but I still offered to post them here for someone who couldn't.

There's another topic for http://www.gamesas.com/topic/1458038-official-tes-vi-location-and-setting-speculation/, this one is for gameplay features and the like. And I don't think you can talk for what is interesting to all gamers, especially those who regularly play TES.

Anyway, I read that Nexus post and I kind of like the whole main quest thing. Basically, I think Daggerfall/Morrowind did a good job with handling the start of their main quests. I feel like the main quest should be handled just like those longer sidequests at the start, but as you continue doing it becomes bigger and more grandiose and you realize "wow, what I've been doing the entire time was preparing for the prophecy from the intro video holy crap".
