10) I don't want to read that again! (Repeating Text)
When it comes to an RPG, as soon as the screen pops up I have read every bit of text there is to read and I am jamming on the X-Button to get to the next bit.
What bothers me is when they suddenly change the focus and ask you a question. In case you WEREN'T paying attention, they ask: "DO YOU WANT TO HEAR THIS AGAIN?"
If a game is kind, the cursor is on the "No" button. Why would you want to hear it again?
The evil games have your option default on YES. As in, "PLEASE TELL ME THE LONG STORY ABOUT HYRULE AGAIN PLEASE." That's right, *bleep* you Ocarina of Time owl! I've heard your stories so many times I can almost recite them in my head. What's annoying is that you're so busy jamming on the A button that you don't have time to change what you are doing.

9) Lack of Health Bars
Remember the days when games were challenging? You had to fight your way through hordes and hordes of villains and you only had so much health to do it! Of course, there was health scattered sparingly around, but at least it was there.
Lately, in shooters at least, it appears that they have REMOVED the life bars entirely! You can get shot in the chest five times, be close to death, and just go around the corner, sit down, and you'll be good as new.
My favorite shooters of all time – such as Half-Life 2, Team Fortress 2, Doom 3, Perfect Dark, etc – all implement lifebars. It feels challenging, it feels like the game is actually trying to stop you. Now, things are just too easy.

8) Franchise tries something different, fan-base hates it.
I am a huge fan of the Zelda franchise. That being the case, their fan-bases can get on my nerves. If you ask most any Zelda fan what their least favorite Zelda title was (excluding Zelda 2 of course) they will say Majora's Mask. Why? It tried something different!
Instead of the same ol' dungeon crawling and sword combat, we got an innovative system allowing for different play styles. It also included a time system. You had three days until the moon crashed, so you had to get things done by then. When time is up you need to go back in time and try new things. You have a pretty unique experience.
When a franchise tries something different, the fans whine. Maybe I'm weird, but I enjoy the occasional burst of innovation.

7) Same game gets re-released a year later, but with NEW content!
This really bothers me, because when there is a game I *really* want, I buy it right away. The problem is, companies sometimes release enhanced versions of the same game later. I wish they would just include all of the content right away, because I absolutely hate not getting the best possible product.
Case in point: Resident Evil 4. The original GCN version doesn't have all the content that the PS2 version has – and even later versions that appear on the same system – and that really bugs me. When I dish out my money for a game, I fully intend for that to be the LAST time I buy that game.

6) Back-tracking
I *hate* playing through the same area constantly. In side-scrolling games, going back to an area repeatedly just gets annoying. The most obvious offender of this would be the Castlevania and Metroid series. I get it, I get it! Your series demands exploration! You get the most out of stuff when you fully explore your environment! Yes, yes, that's great, but I'd much rather fully explore NEW areas.
