Past creations

Other (objects, etc.) concept

Player can find their old creations, their remains or ruins, or some derivatives of them in new playthroughs.

Alternate names: Previous creations, Old creations

For example, a game where player can build settlements in fairly open world (possibly randomly generated one), some of those previous settlements with identical building placements etc. can be found in new games (even if the surrounding regions are different because of the random map generation) with possible some "evolution" to show progress or decay but still enough identifying traits that players actually can identify them (most obviously a name tag).
