The problem with VD is - if he had a kid and they went to a gamestore where the kid would point out a cool jigsaw puzzle he'd really like to do...
If only RPGs were jigsaw puzzles, my friend. If only...
In most cases, the solutions are either painfully obvious and you're clearly told what to do. For every hidden "weak wall that needs some dynamite"-like setup, there are hundreds of "go talk to X across the map and report back" tasks. These tasks are necessary, if quests involve several people, but they are hardly the equivalent of jigsaw puzzles. They are a fucking filler - boring walks interrupted by 2-4 loading screes and who doesn't like those?
Let's take a look at the Fallout 2's Den:
- collect money from Fred - talk to Becky, then run around looking for Fred, then return to Becky, who isn't done yet. Now she wants a book!
- get the book from Derek - talk to Becky, talk to Derek, run around looking for the book, then return to Becky
- Curious Laura wants to know what's guarded in the church - run to the other map, find out, run back to find out what Laura wants next
- Laura wants permission to attack the other gang - run to the other map, ask Metzer, run back to find out what Laura wants next - god forbid she'll tell everything all at once
- Laura wants to find out the weakness - another trek across the map and back. I love playing RPGs! I crossed the map 6 times already just for Laura and have a feeling we aren't done yet.
- Laura wants your help again! Go fuck yourself, Laura.
- Deliver a meal to Smithy from Mom. Yes, across the map. This is why I play RPGs!
- Smithy wants a car part - basically, it's a mental note that once you find a special inventory item that you can get in a certain place and nowhere else, take it to Smithy. Fucking jigsaw puzzles, how do they work?
- Sabotage Becky's stall (finally, a semi interesting quest, but you're still told what to do and in what sequence, so no puzzle there. Oh well...
- Free Vic - the best quest of the Den. Probably the only decent quest, but sadly a jigsaw puzzle it aint. Either give him his radio (no, you can't give him a generic radio, gotta be his) and pay Metzer or kill them all, which is a pretty good fight.
- Return Anna's locket - let's pretend it didn't happen.
