Thrive is a free, open-source game about the evolution of life. From the lowly tidepools of your home planet, you will rise to cosmic dominance. At every step, powerful creation tools and deep simulation mechanics will aid your species’ developmen...
While Thrive was originally widely inspired by Spore’s intended concept, we aim to portray a creature’s evolution in a fun and interesting way while remaining scientifically accurate. Evolution will play out on not just your own creature, but those around you, each competing to survive within the simulated environment.

This line makes me wary of WB
Whats WB?
Warner Bros have a gameplay mechanic patent which has pretty vague wordings.
And although this game doesn’t seem like it’d turn out similar to any of the games they made under that patent, I would expect them to try harassment.
