Lego will always be the superior toy. What's so good about it is that you can genuinely have fun building with it and feel little at the same time. It's stimulating, and I don't feel like I need to 'force' myself to have fun with it and to genuinely play.
Playmobil is also another good one, in my opinion. I've always been into stuff that has all sorts of little figures I can make stories up about.
While I might be into very babyish things when it comes to clothes and accessories, I like my toys being for slightly older kids. Most Playmobil stuff is like ages 4+ I believe. A lot of Lego is like 6+ if I recall correctly. It doesn't ruin my little space though, that is the best way to get into it for me.
What I want to get into more are toys for little girls. I'd love to have some cute dolls I can play house with and maybe a little house for them. Any recommendations would be nice~
