If I'm honest, I think the game is too hard. It has a high skill cap and a high skill floor. It takes so long to learn the game enough to be just good enough to play it correctly. People don't want to stick around unless they have a desire to work at it, and most people just want to play for fun and not bother with all the nuances of GoI, anD then they get crushed and have a bad time, and they never play again. I have no idea how to fix it, but I do believe this is the major problem
You know what other games are hard to get any good? Counter Strike, Dota, Starcraft... You're getting my point?
I've said it before but I can say it again - GOIO is "hard" in a way*, but isn't the problem. The problem is that it can't offer enough for its hardness. GOIO is just not that appealing gameplay-wise. And I'm not even talking like from high horse about the "pro mlg 720 lgbt qwerty" crowd, but even the regular people. Most times when I go back to GOIO I feel I could've been having more fun with other games at that moment.
Also, there is much waiting involved, and I'm not even talking about the lobbies. Let me provide an example:
A) Good design (Rocket League):
I turn on the game
4 seconds of logos
Menu, I press "enter" 3 times and I'm in queue
Usually in match (including loading) within 40-60 sec from desktop.
B) Well... GOIO:
I turn on the game
fucking loader, CLICK CLICK CLICK CLICK CLICK CLICK CLICK CLICK
logos, ESCAPE ESCAPE ESCAPE ESCAPE ESCAPE
phew, menu, two clicks and in queue
[elevator music]
[lobby time, I don't even mind]
And theeeeeeeeen I have to wait (almost always) a whole minute for map load.
Finally, match.
So yeah, people just get bored. We all hate those "c'mon guyz rdy up m9" kind of guys, BUT THEY DO HAVE A POINT, DON'T THEY?
GOIO has this unique mechanic relying on teamwork and truly being a part of bigger machine. It is unique but I think it doesn't let create good stories. We all know that one damn clutch feeling from CS:GO or that pentakill from LoL, but GOIO don't have any stories to create and/or tell really. "I've managed to hit the hull in the last moment" doesn't count as a story.
Also, just saying "program AI pilots" is so easy, isn't it? But we know how Muse works and we've been through much more important issues with much easier fixes not being dealt with, so we know that this kind of project is not going to happen. Perhaps it 'potentially' could if it was just ready code from Alliance (and there are 'some' kind of ships piloted in some way by AI) to put in Skirmnish, but making that from scratch? Damn, son.
*IMO "hard" isn't the best word, I'd say it's overcomplicated at the beginning, when you are supposed to learn like 8 types of ammo at instant but then you figure that for every weapon there are no choices, just 2-3 types that 'do something'
