With series such as COD and AC literally pumping out a game every year (or close to it), when do you think a series has reached it's limit? I know alot of people who don't like or won't play COD due to it essentially being the same thing (more so with MP than with SP) each game.
I feel a series has reached t's limit when absolutely nothing new is being brought to it. I don't mind staying in the same time period or whatnot but it seems that after a game's trilogy has happened, they don't know what to do and make a half assed game. Obviously there are exceptions (Final Fantasy for one) in which the series offers something freah or can keep the story so inviting that it can go forever.
As far as reboots, Tomb Raider has seemed to pull it off wonderfully from what I have read as I haven't played it yet. Then others like Duke Nukem can't seem to do anything right. Do you feel reboots happen, like in movies, because a company has no new idea to put out? What does a reboot need to do for it to succeed in your mind? How long does a game have to wait to be rebooted?
