TBH! If it's just a bunch of hand crafted plants with colour variations, I suspect that won't interest me very much
Exploration is all about the chance of finding something different and ideally fairly unique. Hang crafted plants don't tick that for me
A clever procedural engine generating plants based on a good number of inputs I suspect would tick that!
Plants should be fairly rare, should generally follow certain similar themes, but there should be the chance of real curve ball/extreme/odd examples very rarely!
