_{[Every week (usually Mondays), Destructoid will pose topical a question to the community. Answer it if you want!]}

The games industry seems to be rather fond of remaking the leisure products of yesteryear with fancy, high-definition graphics to bring them into the modern age. Are these releases introducing new audiences to the classics, or just exploiting nostalgia? Does it represent a creative drought within the industry that we see so many of these upgraded releases and so few original IPs? Is it an effective way to keep a series alive between installments?
