I voted yes in this topic, and I also personally rate V a solid 6.5 or 7/10, but it still doesn't feel like GTA to me. Limited storage space for vehicles, 3 characters which just feels "odd" to me, nothing to do after 100% in SP (which is all I will play), no proof vehicles which have been in these games since GTA III, stupid helipad/hanger system, silly DLC's that add vehicles that I may or may not be interested but this only means I gotta get rid of an already fully modded and stored vehicle just to store the new one, Rockstar concentrates only Online and adds everything to that nonsense + more storage space, cop system is just f*cking bogus with 99% accuracy, cops with NOS in their vehicles, short story, boring asset missions, I can continue if you need me to. This game sucks as a GTA title. But as a NON GTA TITLE, it's a good game that does NOT deserve the name GTA.
EDIT: Also, like the guy above me has said. How on Earth can you control cars in the air? How can you flip them back over when upside down? It might be a "helpful" feature, but it's total pussy bullsh*t. Rockstar just keeps making these games more and more casual, it's not in the true GTA spirit, especially for someone like me and the next guy who's been there since the start of either 2D or 3D. Personally, I started with GTA III and own III, VC, SA, LCS, VCS, IV, TLaD, TBoGT, and V.
V is the worst.
