I won’t buy it because they focused on the graphics too much and fucked around with things that were working great in CS and CS:S. Now I normally wouldn’t say that but seriously… my laptop can run CS:S and Portal 2 at a constant 300FPS at 1280x1024 but CS:GO didn’t even want to start up until a very recent update, now it’s not much better though because it is pretty much stuck on ~1fps the whole time.(core 2 duo, not intel graphics either) Also they removed mat_dxlevel, mat_picmip, r_lod r_shadows and all those useful commands from the console. I can still play it at good framerates on my desktop, until I found out you can’t spray tags anymore. That was the final straw.
The only thing it has going for it is built-in gun game, but even that is kind of fucked up…
Gungame (Arms Race) mode has 2 possible maps but “Demolition” - a shitty version of gungame with only 10 guns has at least 4 possible maps you can choose from.
