I am a really big fan of base building in RTS games, which is why I never liked Starcraft. Bases in Starcraft feel like they have such little rhyme or reason. They are messy and ugly. I always build a ton of bases in games like Tiberian Sun, that, while gameplay wise, are a waste of time and money, feel fun to build and fun to defend and destroy. I think a really cool strategy game idea would be a logistics themed game. One where building more realistic bases all over a map is a strategy so that they can supply and support each other. Maybe you start out with a FOB and you need to expand into guerilla held territory, but you need to build COPs and Logistics centers to keep your troops supplied and protected.
I always hated in Starcraft how clicks per second is a means to measure how effective some one is at the game. I really want to see a game where tactics and unit composition matter, where a platoon of mechanized infantry face off against like a BTR platoon and, using strategy, you pull through. Have each squad with a realistic composition of like a Squad leader, 2 team leaders, a radio man, 2 squad weapons, a crew served weapon, 2 anti tank units, a combat life saver, and 2 rifle men. I think something with that depth, but with a more coherant interface than like Shockforce, and with pausable real time combat would be awesome. Like Arma but an RTS.
More minecraft open source clones. or a modded community version of mc that works without microsoft. The game belongs to the community and I think we should take it back from the corporation.
Most of them are cash grabs or cheap knock offs. I want more voxel games that are built with passion that can stop microsofts monopoly. An alternative I think would be cool is the community modding microsoft out of minecraft with special accounts that do not rely on microsoft. Luanti aka Minetest looks promising as an alternative.
VoxeLibre is a game that can be installed in Luanti engine. It will make sense once you open Luanti since the first thing it prompts you to do is install a game from its game library. VoxeLibre is one of the first listed.
