My dd loves anything that has a million parts. I got sick of trying to make her pick them up all day every day (and it would eventually be me picking them up), so I started putting the legos, dollhouse stuff, play food etc. on a shelf in her closet. Now she has to ask me to get them down for her. Before I do, we pick up the toys that she had already taken out. It's helped me quite a bit. If you just want to clear out some of the clutter, maybe you can put some in the attic and just rotate them out. The donating thingie sounds like a good idea too. I took a lot of toys to my dd's preschool recently.
