Well you are able to destroy walls/roofs to gain an advantage on your enemies unlike CS:GO.
Besides it's a new game vs an old one, there's bound to be less maps. Nowadays all shooters seem to launch with few maps.
Not just that, but with each character's ability, the way each round plays is unique, which causes strategy to constantly change. This is very different from a linear game such as cs:go. I also don't mind the micro transactions. While I don't care for the cash grab nature of it, if people want to pay more for less grind or skins (and presumably help fund dev costs), I'm fine with that when, such as here, it's not pay to win. I've had the game for 2 day's and have half of everything (minus skins unlocked). Besides i usually play recruit, as it gives my team a heads up that I'm still learning the game and allows me to try out various weapons and play styles.
Honestly, this is by far one of the most interesting and challenging shooters I've played in years. I'm also kind of glad by the fact that there are only 11 maps as learning them is vital, and their complexity is substantial unlike CS. Not to mention that while CS launched with 16 maps, how many of them do people regularly play?
