Project Rene, the in-development follow-up to The Sims 4, is shrouded in mystery. Despite not knowing much about the game, it's likely that the next entry in the long-running life sim franchise will expand upon many features in The Sims 4. Project Rene has its work cut out for it, since The Sims 4 has been continuing to build upon itself for a decade now. Through updates and expansion packs, The Sims 4 offers a large variety of lives to jump into, which could be hard for Project Rene to compete with at launch.
