I feel like the game mode system is nearly perfect for how long it has been around. Of course there is improvements that can be made, but it is awesome for what it is. You can play the game how you want. If you don't want to play career you don't have to. If you want to just gain science you can. If you want to make career harder or easier knock yourself out. It does slow updates but the game is in a really good place for players, and there are a ton of mods to boost your game play. There is not a lot of complaints anyone can have for squad giving what they do for us.
