If I were to pick a franchise, I probably would prefer to kill off The Crew in order to bring back Project Gotham Racing. There were many things I liked about The Crew games such as the car selection, the big map, and gameplay styles. However, the game still suffers from issues like being an online focused game (which really ruins the core gameplay for me when it requires an internet connection), a horrendous economy, bad arcade physics and controls (still having to shift with bumpers and horrendous weight transfer with the cars).
I honestly could see myself enjoying a modern Project Gotham Racing game over that game. Sure, I wouldn't have free roam, but I can live without that if the core gameplay is focused. Especially if the game expanded on the locations used in a hypothetical PGR5 like Bizzare Creations has done in the past. The arcade physics were fantastic, the cars did slide around, but they always felt controllable and were grounded. I could really shift the cars around and have fun with them. Not to mention the amazing car sounds used in PGR4. Oh god how I miss this series.
