With the beta coming to a close, I think Modern Warfare is a promising game that takes some serious adjusting to. Whilst it does bring back a lot of old headaches from around a decade ago, it also does a lot of things very well that we haven't seen this gen. The PC version I found to be very impressive and quite satisfying to play which almost felt like COD 4 at times. The PS4 version was decent enough but felt somewhat dated on my ageing first gen system and had some horrendous post-processing effects which thankfully could be disabled on PC.
I felt I adapted to the maps in the end and whilst matches seem faster than they initially appeared, I do think a couple are OTT design-wise although matches seem to flow pretty well even if they do appear very big. I never felt lost or starved for action. Guns feel good and the gunsmith is a neat implementation and could make class customisation very detailed. Killstreaks seem fun once again but UAV spam seemed rife. The interface could be better and I hope kill confirmed will return also. Crossplay is an excellent feature to have.
I do fully understand why people don't like this game though. I have had a few matches where I was just not having fun whatsoever and frustrations were aplenty. The spawns need work and there were other things like bullet effects going through thick walls which looked trash. Annoying campers and terrible teammates were a stark reminder that the experience isn't always going to be enjoyable and with other small irritations, you have to ask yourself if you're willing to go through all that in the hope of having some enjoyment.
On balance, I will probably get the game but it is way too early to gauge its potential long term appeal and overall quality. The campaign and special ops I am also interested in and it'll be nice to see what other maps are on offer. Here is my final match of the beta going 27-10 on Grazna Raid Domination which was great fun:-
