We run a review site and what we consider to be most important are exclusive games. It'll be hard to position yourself if you offer the same games as all other casinos. If, on the other hand, you work to add new and innovative games you can draw a player base of users who are bored of seeing the same 300 games by Pragmatic play on every casino.
You probably have a shot if you also complement this with good bonuses and promotions to draw new players in.
It's a tough market out there. Best of luck!
