I don't think those comparisons are fair to make. GTA V has been developed by an established studio, while CIG has been built up from scratch. Rockstar already had an engine trailered to them ready made with the support from several of their studios. CIG have been running and supporting a live multiplayer environment since 2015. Also all three of your variables - scope, time and budget - have been dynamic and mostly increasing, while progress has been made. There's obviously a problem with scope and time management, but I don't think criminal levels. Apples and Oranges (with a development goal of pumpkins)
