I've never been good at the Metroid games. I beat Prime 1 and Fusion with the help of guides, but when I try to do things on my own, I get easily lost and bored because I wish they had a warp feature like in the Metroid-vania Castlevania games. I really hate the constant backtracking.
Since I never had PC games growing up, I expect I would suck hard at RTSs. I might be okay at them, with time, but I never had any practice.
On a related note, I'm horrible at tactical RPGs. Even ones that are considered kinda easy like some of the Fire Emblem games, my luck is terrible with these games. They all take too long for me, and I always try to make sure that none of my units die (if they can't be replaced), so I screw up a lot. Which makes me feel bad because all my best friends kick ass at tactical RPGs.
Speaking of RPGs, I tend to suck at games that have one-click combat. Oh, how I ABSOLUTELY F*&%ING HATE one-click combat. My first time with it was with KOTOR, and I practically rage quit because of the combat system. Then Bioware brought it back in Dragon Age, the bastards. Boring ass shit, easy to screw up (in my opinion), and never fun. The only game that had that kind of combat, but better, was Xenoblade Chronicles.
