it is a bad thing because theres 0 progress between games. and the stuff they added to online for 2 and BO was such shit people were just throwing random nades to start their streaks and then hiding using all their perks throughout the map. MW was the only "good" game from MW, MW2, BO. Most of its campaign missions were easily fun to replay its graphics were up to date and its online had the perfect balance of perks to where being good at a FPS actually mattered. everything sence just crippled it. only 1 or 2 missions were replayable in its successors, they filled the online with so much shit perks you didnt need any skill or any gun to kill anyone else, and the graphics NEVER progressed...in 4 years its been the same engine and the same level of graphics. and frankly 4 years in this day and age with 0 progression is just MEH.
