I have pieces from original sets, but there are also many imitations, such as Chinese sets, which were bought for me as a child, because small Lego sets used to be very expensive at that time, while large craft sets were cheaper.
You know what’s funny, is I think the face printing and logo on the slope piece are actually Lego decals from Classic Space
Honestly, with the price of lego and their own deviation from the “Lego” aesthetic in recent years I wouldn’t fault anyone for sticking with the clones. I have used quite a few of the “compatible” sets from China and other than the logo on top of the studs they are identical. Even the colors are on point these days.
Any clone brands you recommend ?
I would think the issue would be for obviously non-lego pieces. Not knockoff stuff, but like, K’Nex or something clearly not interoperable.
I wouldn’t clock any of the pieces in that picture as non-standard, personally.
