I think too many "adventure" games are adding puzzles in place of the usual lateral thinking excercises because, in my oppinion, they CBA to come up with anything better to challenge the players. Broken Sword 3 had a bunch of tedious crate puzzles (you ha to move a series of crates to get over walls or through windows, etc) and BS4 had this seriously annoying "hacking" puzzles where you had to use the main character's PDA to get various information from the web where you had to make a line (that represented the line between you and the server you were trying to hack) reach a certain point by bypassing certain obsticles using reflecters and all sorts of rediculous crap. (The whole thing just sucked and not just because of the stupid PDA puzzles).
I know these might not be what you mean, necessarily, but if the developers of action games don't watch what they're doing they could end up adding things that detract from the game completely. A lot of people felt this way regarding Monkey Kombat. (which I liked, personally).
Maybe some mini games, to be played separately, could be packaged with TBI? maybe not even packaged, i dont know... just a little extra dose of piratey goodness as a bonus
