I got the idea for this topic after watching a video on gamespot the other day. It talked about how Resident Evil 4 is an absolute classic, but has led to a very bad trend. So I thought what are the games that you think are great and/or classics that have a bad legacy instead of a great one. Here's 2 that I've come up with:
1. Resident Evil 4: The game transformed the RE series and gave it a much needed facelift (at the time). It restored the scares that were missed in Code Veronica and increased the tension by making the scenery much creepier and increasing the pace of the action. However, it has led to pretty much the death of the survival horror genre. The scares are gone and it is just about action now as evidenced by the Dead Space games and Resident Evil 5 and the even worse Resident Evil 6.
2. Call of Duty: Another great game, that made WW2 games feel much more like actual WW2 battles by making you part of a squadron instead of a one man army. However, it's crimes are too numerous too mention, not the least of which led to every FPS being a CoD clone and the death of innovation.
