Umm, yes, very yes

I don't really care about Garrus. And to play an entire Game as him would be too much

No since that sounds boring. No offence

Only if it were a genre spinoff, not a traditional BioWare entry. Garrus is Garrus, not me. An excuse to have an adventure in the world on an interesting plan- area is fine, but don’t lessen a good character to prop up or sell a game.
