I do think the Command Center is essential to the fun and strategy of QONQR. I'm a two-week old player and so I don't have any nostalgia towards the old metagame style so I may not understand that part, but I like seeing any type of change that would make this game more complex and bigger.
I think whether to keep this application boils down to a few scenarios playing out if CC and the API is withheld: First off, players are forced to manually check each territory. Most teams will probably assign different ways to effectively catch any invasions small or large. Techy peeps can, and probably will, create some sort of bot that can digitally track each base and their numbers and report the difference. This gives them the advantage. This is a sci-fi game and any sort of quick electronic intel should be encouraged and given to all players.
Personally, I'd prefer if the CC was part of the game itself. I think that it's an expected feature for new players like myself. I also think it would help retain players to stay in the game. There could well be a massive battle 4 bases away and I wouldn't even know about it. Then I'd could possibly be bored out and leave the game thinking there were no action for months.
Anything that promotes non-introduced team members to work together is a plus. It's how friends are made and it's why we play online. I almost quit the game early on if it weren't for me randomly messaging a fellow teammate on the local leaderboard. As a self-kept introvert, I almost never message strangers unless I've had good, game-related interaction to where I know we are somewhat on the same page. Right now, I have no clue as to whether my friend is still playing for the past few days and I don't want to msg him every day to find out. I'd rather just log into the game and check if he sent out bots in our area. Also, our enemies are doing a spectacular job finding where we are hitting because they have dedicated people checking a certain region off. My team is way smaller and spread out (there are more than 20 enemy bases between my closest known ally) and don't have the man power to manually check surrounding bases for action. This gives us a serious disadvantage and crushes any hopes of ever gaining any territory in our area.
Anyways, I support the use of this feature even if it's only on PC. Maybe it can be limited to timed "scans" per hour(s) or time of day, but ongoing battles that lasts a day or so should be known to all local players.
