bruh, no. if that were true then we would've had gta v a LONG time ago. compared to assassins creed's 8 titles. you have historical events that include naval battles, assassination contracts of important historical people, weapons customization, armor customization, awesome combat maneuvers, etc.
It took rockstar games 5 years to make Grand theft auto 5, so many people have been waiting for a very long time, the results, a fantastic open world available for you to explore at your choosing time with a variety of things able For you to do. Making over 1 Billion dollars in the first 3 days. Though assassins creed is a well made game, after you beat the main mission, there is almost nothing to do, and if there is, it gets repetitive over time, with grand theft auto, it's not like that, it has many side missions that will keep you on your chair for hours.
