these are the reasons why mainstream gamers dont like the opflashpoint/ arma series.
slow UI's are just a by product of a complicated game
The reason mainstream gamers have never embraced any of the games is because they install the demo and it runs like total dogshit, they turn their settings down to stop the lag only to find that anything other than max settings looks like you're playing on a N64.
The UI is fast to use and extremely simple, that isn't what I was saying, it may be easy and fast to use once you learn it but combined with the usual performance problems it feels terrible, 2 games and 5+ expansions later and basic things like accessing weapon crates still feels (and looks) terrible...* click middle mouse
* awkward bend down
* awkward lag
* scroll through 50 weapons to find the mod you want
* attempt to click a loadout button you don't need
* awkward stand up
At this point a lot of gamers are going "do they even want me to play this game? I honestly know people who have been driven away just because of the base stupidity in the way the weapon selection works (which the next game appears to have fixed thankfully) and because they HATE every single one of those stupid voices in the game, it's just not professionally made.
If they had half a brain then accessing a crate would go:* click middle mouse
* weapon inventory instantly opens (character crouches in the background)
* select weapon
* select mods from drop down boxes for each moddable position
* click button
The same would work for the backpack interface:
* click pack in inventory to open extra inventory window
* drag items into backpack (with clear indications of weight etc)
rather than just having the inventory open and go HUUUUUUUURRRR
ARMA fails for the same reason most MMO's fail, people don't have any tolerance for junk these days, a game needs to work reasonably on launch and it needs to scale well with graphics settings. Default ARMA doesn't even have any features, modability might be nice but they barely added a single new feature over numerous evolutions of the game.
Those guys fell so in love with Flashpoint that they just keep making the same game over and over and over again, everything that ACE adds to the game should have been standard features for everything ARMA and beyond but it still gets left to amateurs to beef the game up (and they continually do a better job than the pro's do).
There's no reason they can't have all those features at launch AND make it easy for people to drop in and learn, if they want to just stand back and let the community do the work then they might as well just quit making games and start selling engines because ARMA in all its recent incantations may as well be Unreal Tournament 1/2/3/4/5/6.
