My ds is 3.5 and these are the toys we have loved so far:
Imaginext fire station
Brio train track
Tomica hypercity train set
Playmobil car wash
Whiteboard
Balance bike
Play doh sweetie cyclone - adores this but not much interest in other play doh sets.
Tool box and tool kit
Marble run
Stuff that he has pretty much ignored:
Step2 play kitchen. Bloody expensive and ignored since last Christmas.
Any character toy (only exception appears to be fireman Sam. Not bothered with any other character toys and they all seem so badly made)
Playmobil boat (not interested, had no wheels)
Mobilo - no interest in building
Mega bloks, never ever played with, not once.
We have a number of in the middle type toys that get a bit of attention occasionally but aren't played with as frequently as most loved toys, yet are still played with often enough to stop me chucking them out.
What have your dc liked or not liked?
