For both kids, in our lounge we have a small toybox with various toys (stacking rings, wooden puzzle, shape toy, train track, stacking boxes), a box of wooden blocks, a Playskool Weebles toy, table and chairs with pens/paper/playdough. Everything else is in their rooms. They mostly play in the lounge, and I will occasionally rotate the toys from their rooms into the lounge. Sometimes in the afternoon we hang out in the bedrooms and play with everything down there, so it does feel to them like rediscovered toys. I think rotation is a good idea. What I would do is leave about 10 toys out for him and see what he goes for. You will be amazed at how differently he plays with them - before I removed the bulk out of our lounge, things were just getting tossed around and gone through rather than any substantial time being used to play with anything.
