Haha well I only meant to sound frustrated... maybe even slightly annoyed, but not angry. So don't take my words too harshly. TBH i haven't played any of those games u listed. I grew up playing Halo though, so I know first-hand how important the series has been for console fps games and the fps genre as a whole.

Anyway, sorry if I came off too harshly. I'm sure you have your answer from the other replies, and it sucks that you felt the series was too same-ish and easy. I would recommend the solo lengendary experience to change that. Might sound like a nerdy waste of time, especially if you couldn't immerse yourself into the point to point nature of the campaign, but every battle will feel intense and unique, depending on how u do it
