The amount of unique situations in Rainbow Six Siege makes it stand out among tactical shooters. Attacking can be fun sometimes but defending involves checking cameras, holding angles, rotating and patroling, and I seem to always come back to this game over Counter Strike, for example. The shooting experience is also fair and satisfying. I don't know, it does some things great and then the community and the matchmaking system are quick to ruin the experience in the end. The game is almost 10 years old and there's still a lot of potential.
