I rarely worry about most of those things in paid games anymore. It tends to be a problem in free-to-play stuff, but not generally as much in games you actually paid for. At least when it comes to these specific types of artificial resources. DLC is another matter. Generally what ender says is correct, it's only people with way too much money, zero sense, or a sincere refusal to spend any more time than necessary who go for this sort of thing, and usually everyone else is safe.
Who knows, here, but my guess is it'll be fine, recent Konami evils or otherwise.
I also highly suspect that Kojima ends up somewhere else. Anybody'd be lucky to have him, too.
Many Japanese game companies made something else before they became game companies (Nintendo with hanafuda cards, Koei being a dye company, etc.). I think the corporate mentality there is a bit different than here. If they struggle too much, they may just jump markets if they've got some momentum going in another arena. I don't know a lot about the history of many game companies, but I know many companies in general in Japan have existed for a long, long time.
