Like others have stated back in the year (2013) I also wish was better at fighting games, like Tekken 3 for example I can probably beat 4 or 5 fighters on Medium difficulty but after that in order to win the next fights you need to learn to use all the controller combinations to win, I just get board learning all the combos in training and I probably need to write all the combos for each character down.
and like others have stated on here I wish I was better at shoot em ups and all platformers.
I also suck at Metroid for the NES classic because I can't duck and I think thats stupid. that I can't kill most enemies that are on the ground,I mean why the heck can't I duck and shoot those ground enemies in Metriod? Its boring getting killed by an enemies that you can't kill.
I wish I was better at Spiro: Year Of The Dragon PlayStation 1, in which I got stuck on a skateboard arena level where you are forces to keep moving forward and can't slow down or stop and need to perfect multiple 360 jumps I keep crashing and I can't make it without wiping out.
I wish I knew how Red Faction 1 is programmed so I know what I keep doing wrong on that terrible stealth mission, the guy that got farther than me on YouTube was just strafing in the open and I still don't know how he did it.
