What should we call this real time strategy subgenre of games which are designed with base building and defence gameplay, mixed with horde/wave survival and often having some tower defence and/or roguelike elements as well? This RTS subgenre I just described has been growing even before They are Billions came out in 2017, but has certainly exploded in popularity since then, including Diplomacy is not an Option, Here Comes the Swarm, Age of Darkness: Final Stand and upcoming games like Repterra and Dawn of Defense. 💥Here Comes the Swarm Tutorial:    • Here Comes the Swarm Tutorial for beginner...   ✅Calyx gameplay Guide:    • Base Building & Campaign Guide on Calyx! L...   ⭐UPCOMING STRATEGY GAMES⭐    • New & Upcoming AAA and Indie games   👓Game Previews:    • PC Game Previews with gameplay and features   Chapters 0:00 Name this RTS subgenre? 0:36 Games like They are Billions? 1:35 A jumble of Steam tags… 2:04 Core gameplay feature? 2:18 Base building? 2:39 No enemy base? 3:20 Name taken? 4:22 A challenge for you! 5:00 Something in common? 5:35 Non based enemy RTS? 6:36 Active pause system 7:03 Gateway games to RTS? 8:04 Self imposed Hard mode 8:52 Enemy Horde & Waves 9:31 Horde Defence RTS? 9:59 Survival 10:27 Developers & Innovation 10:56 Poor man’s RTS? 11:27 My name suggestions 11:54 Conclusion 🛒Links to all games: They are Billions - https://store.steampowered.com/app/64...
