Personally. I agree I'm guilty of this. The last Dragonball Z series of Games I played was Budokai/Tenkaichi and they were fine. When they made the move to Gen 7, they lost appeal to me and I never looked back. Friends had them bur I never went out my way to buy them anymore.
Games like Call of Duty, Madden etc, they do their job. They are designed for the people that have Gaming as a secondary or even tertiary means of entertainment. They play video games say 2 hours a week with friends when they come over before going out to a club or making love. These sort of games are designed to offer cheap thrills to those that don't spend a large portion of their time on video games, which is why I opted to go for something that is designed for those who have gaming as a primary for of entertainment.
Even games like Mario, which I would be glad if it Mario platformers dropped to a 2 year schedule rather than a 1 year schedule, are designed with these players in mind. I know I'm pretty sick of Mario games just now.
