For people like me (and maybe you too) this is almost deadly though. In Morrowind I'm so caught up in the length, variety, and quality of the factions available to join that virtually all of my characters are defined at least in part by which factions they join, and how they complete them. With Skyrim it's pretty hard to do that, or make each character different. If I want to be a warrior and a part of an organization I pretty much have to join the Companions, and then I have to become a Werewolf, and it's just all so drab and under-realized compared to even Oblivion, but especially compared to Morrowind.
And all in all I feel like the radiant quests are a little bit of a failure. Especially as to how they related to guilds - it's just not the same when there isn't at least a cursory back story to what's going on. And the Thieves Guild is the worst, their radiant quests boil down to 'Hey, we need you to steal an item that we've implanted a GPS chip in. Here are the coordinates, go pick it up and bring it back. Nah, I doubt anyone will catch you - so easy a caveman could do it, am I right guys?'
At least the Jarls bounty quests are okay, they give you a little note. It's just too bad the rewards aren't more substantial/varied and the people you're sent out after aren't a little bit more unique/varied too.
Exactly what I was going for. I do feel the Radiant stuff can be good though. The Companion's quests make great use out of Radiant story to fill out misc objectives, which if you were to put that in the context of the standard Fighter's Guild (Oblivion, Morrowind) would have been a match made in heaven. (Since almost all of those are Go here, and kill this, or Find this, and bring it back).
Radiant doesn't work so well on say... The Dark Brotherhood though. Which actually dodged a bullet in Skyrim by making the Radiant quests active only after completing the main story (Thus entirely optional). To elaborate, I just feel "Random NPCs" really undermines the idea of "Murder" as in taking another life. This is probably why I don't like Respawning Bandits/unamed humans too. They have no Identity, might as well be a wolf with armor.
Reward quality is a problem though. Gold is okay, but eventually it does become pointless. I'd rather see more Long-term rewards for Radiant questing, similar to what the Thieves guild does. Trophy Items, and improving the Guild. For example, doing a lot of Bounty Quests in say, Whiterun hold could improve (Slightly) the Merchants available gold, and they might carry rarer items more frequently, since the roads are being cleared. Then, as a coup de grace, after many bounty Missions, a Courier gives you a letter to meet the Captain of the Guard, who has a very important, and very difficult hand-drawn (Not radiant) bounty contract for a particularly nasty enemy. Stuff not "Normally" encountered in game (Unleveled, extremely hard). For example, Whiterun Hold: Armored Giant Warchief. (See; Torfang, Horror of Castle Xyr). Rift Hold: Comonna Tong Kingpin. (Orvas Dren, except lore doesn't state if the Neravarine killed him as of the events of Morrowind, similar to the fate of Vivec)
Oh well, no point in waxing on about missed opportunities.
