Radiant quests should have been optional. You don't want to do it, you don't have to. But if you want to spend some time in the wasteland and have nothing to do, these quests could be used to pass the hours, provided there is enough variety to keep the interest going.
Some things that might improve them, maybe:
- was your character in x location recently? Avoid placing the quest objective there.
- just finished the same quest in the previous settlement? Set its priority to low or place it at the back of the line.
- has your character been everywhere n times already? Move some junk around to simulate activity in the area.
- fix, craft, build, kill, heal, plant, talk, buy, sell, protect, escort, defend, steal, reverse-pickpocket and whatever else there is... If you've got the mechanics for it, mold them into radiants.
If you want to use something in your game, do it right or don't bother.
The more depressing is MMO feel behind them really. Kinda looks like Bethesda feel their way to another MMORPG but in Fallout universe.
You should try The SKIES alpha. It's crap at the moment and it will probably be crap later on, but it should give an idea of how a Fallout MMO might turn out.
