It doesn't say Tomb Raider made a loss, it certainly doesn't even remotely indicate $100mil on advertising.... you're talking about advertising at that price on the level of the disaster that was John Carter.. .it's insane to even misread any of that as $100 on advertising.
It doesn't even say Tomb Raider cost $100mil, it's a general "if a game costs $100mil they need to be beating 5mil in sales".
It ONLY links to an article which says due to SEVERAL titles not hitting sales targets the head honcho has stepped down. 3.4mil sales is great, it's more now. More importantly the situation is not about profit with these kinds of companies, it's about how much profit, and the profit from projects like Tomb Raider needing to make up for losses on other projects.
Their sales target could have been 5mil, and that could have been a $200mil profit target, at 3.4mil it could still have made $130mil profits, it's just not what they wanted because two other games made a $50mil loss each.
On a personal level I have no problems with IP's making varied types of games, the story is the IP, not the type of game it is. I don't expect that Lara lives in a world where every treasure and situation she would be in would be in identical locations. It makes sense to be in different situations in her life and this will lend itself to varying styles of games.
THe only issue really is when people expect more of the same and then buy a game they didn't really want, I can understand that is frustrating.
Then again plenty of games stick with the same genre/style of a game, and completely screw up sequels so it doesn't really matter does it. A good game is more important than if a game is the same style as previous games. DA2 is god awful but the same style, the current COD games are woeful compared to the 1/2/4, but they are the same type of game.
