I think that your words are too hard.
NWI is a small Team working hard on this title and they do listen to their community. More than other bigger companies do.
Give them just some time and you will see they will fix and optimize as good as they can.
The community manager said that they will support the game with new content ( maps / weapons ) and do the optimization and bugfixing for some years ( i believe he said 3 years )
So be patient and enjoy the game as it is ! The game is much more fun than any Battlefield title in the past and World War 3 and even Insurgency2014.
If you think the game is too easy i propose to play on custom game servers where the bot count is much higher.
By the way many people are already working on old Insurgency2014 maps to make them work for Sandstorm building them with Unreal 4 engine.
As soon as we get new custom maps and weapon mods the more the game will be played. It´s just a matter of time.
With the next official update ( hopefully at the end of this week ) the "GPS guided Molotovs" will be eliminated which is one of the biggest problems ( concerning coop games ).
Also the jittering characters / bots should be fixed with this patch.
In addition we get votekick option for custom servers , so what else do you want ?
The game feels very intense and immersive. Without exaggeration i can say Insurgency Sandstorm is the best FPS game i have ever played on a PC !
And just for info, i played a lot of games until today. I am 47 years old and i play computergames since 1998 !
I admit that i mostly play coop mode but even versus games are fun.
In my PC there is a stone old Nvidia GTX 780 Ti graphics card and in most of the games i get 80-90 fps and the game feels butter smooth.
So i have no idea what your problems with the game are but i am sure there is nothing that cannot be fixed ( sooner or later ).
NWI you did an awsome job with Sandstorm !
Thumps up, keep up the excellent work !
