Pokemon in the sense to have an enjoyable fight with a random person on Wi-Fi you need to understand the deep gameplay underneath Pokemon which is not taught to you what so ever in the main story/single player game. In the game the tactic you learn is the 'Rock/Paper/Scissors' tactic and equipping your Pokemon with abilities that willgive it a fighting chance against types who'd otherwise destroy it.
With the Wi-Fi battles you need to be aware of EV's,EP's EA's ET's etc as well as Natures and even genders. You must breed and breed and breed again Pokemon and train them in certain ways. This is a tremendous amount of work and at this point it stops being an innocent and shallow fun game. It turns into work.
I enjoy Pokemon. I just don't want to invest X many hours in an anti-social portable game to create the 'perfect' Pokemon. If it turns out you made a mistake, it's a lot of time you wasted.
HoN/LoL/Any Competitive game where losing has a negative effect on your statistics. People don't want to lose. They'll do anything to not lose. They'll rage at people who they see as the reason for losing. You try your hardest, push yourself to the limit and feel let down by your team mates or opposing team's choice of characters. If they removed the 'penalty' for loss then perhaps they might become fun again. But maintain a good reward for winning so people actually want to win, oppose to 'avoid to lose'.
Youtube. I posted a video 5 years ago of me playing a Frostmage in PvE cloth armour clicking in WSG. I even now get flame comments saying 'clicker noob!'. Dude. This was 5 years ago. Don't you think I'll have changed to using keybindings now? Ofc not. You're a retard. Also, on videos of a 'gay nature' you have shitty comments of homophobia. Like... why are you going on these videos where the thumbnail and title heavily suggests these themes anyway? Same can be said of music videos.
Also, when people upload videos of themselves singing/playing a music instrument, users feel the need to flame any imperfections. Constructive criticism is win. Tell them how to get better and they'll be less likely to insult your ears next time. Especially when the uploaders are only young. I bet you feel big trampling on the dreams of someone 10 years younger than you.
General internet users who use short hand speak. The only time I'd excuse this is in Twitter (or any other strict text limits) or general chat in an online game. In forums or Youtube comments you have the decency of trying your hardest to type things out proper. If you are insecure about your abysmal spelling then use Google Chrome. It attacks you with sguiggly lines of death if you misspell, then you simply highlight the offending word, right click and choose the correct word. For a start it will help your spelling.
FPS game. Woop, you're better than me because you use a proper monitor while I have squint-o-vision laptop one. You're so awesome at this multilayer point and click adventure game. Woop you're raging at me camping, I'm sorry, last time I checked in real life you don't run around battlefields like a twit, also if I did you score a point, and if you have a brain you could work out where I am. Woop I killed you with guns that kill. The people who get 'over excited' in FPS games must be tetesterone whores.
Deviant Art has the complete opposite of Youtube. Everyone is too nice. You do a picture. Upload it. All comments are all "I Like". Wow. As an artist that's so useful. That really will help me improve my craft. It doesn't help that 75% of the images on there is bad art or badly disguised porn. If you're going to do bloody art, do it well. You're just insulting me and professional artists around the world otherwise. I know art is subjective. Quality isn't. I don't like how a lot of users see Deviant Art as a form of Facebook where you coincidently upload bad drawings of Anime/Video Game Characters or terrible stories. It should be the other way round. And if they really care about their drawings and text constipation then they should seek ways to improve it. The Lovey-dovey userbase doesn't help.I would prefer the douchebag mentality of Youtube on Deviant Art. For a start it will provide an accurate representation of the public's thought of art. Humans are harsh. The majority of users on Deviant Art I doubt are human. A young user actually thanked me for giving her advice and she also didn't like how unhelpful (despite nice) all the comments on her work were.
Doesn't take a lot of effort of being critical. "Oh, it looks a bit flat. Perhaps it's not dark enough under the apple". Every criticism has to be matched with a suggestion of remedy or imply you went to the effort to think about it. If you don't want to be blunt, try sugar coating it by saying "Have you tried life drawing of people?" (Your figure looks very wrong)or "Have you tried using x medium?" (Crayons/Colouring Pencils/Felt tips look very shit. Try a similar medium which will provide better results with your little knowledge and experience. Perhaps then your work won't look like something I'd wipe my arse with.) Easy isn't it? If you can't say anything nice, say nothing. If you have to say something nasty, say it in a nice way.
