Drawing inspiration from my recent experience with the latest two Smash Bros. games, I have conducted a "chart" depicting what a PineappleProducer goes through when playing Smash Bros. Perhaps I need to seek some help.
Stage 0: Pre-Release Hype
OH MY GAWD! ITZ A NEW SMASH BROS, BOI!!!!!!!!!!!! *proceeds to giggle like a little girl in excited anticipation*
Stage 1: Initial Playthrough
You are having a blast playing through the different modes offered, and feel like this game is the second coming. You easily clock in 4 to 5 hours in one sitting.
Stage 2: Subsequent Playthroughs
Your initial excitement has leveled off, but the game is still a load of fun. You're still playing it at least once a day.
Stage 3: Boredom & Irritation
You've done unlocked all the characters and stages... already... where's the fun in unlocking anything if they practically just give it to you? The modes you thought were pretty cool now feel more like a chore. Your heart isn't quite in it anymore, so your game begins to slack. As consequence, you begin performing worse. The AI of the computer players starts to irk you.
Stage 4: Rage
The final straw. The cheap-arse AI has become too frequent an occurrence, everybody online has made you realize how pathetic of a player you really are, and the ridiculously inhumane challenges keep tearing you a new one. You find yourself cursing and screaming to the point where your head constantly hurts, and wish misfortune on all who concocted such an abominable atrocity. You take the game out of the console and want nothing more than to grind it to a fine powder, but then you remember you paid money for it.
Stage 5: Resentment & Abandonment
Knowing deep down that destroying the thing would be foolish, you put the game in it's case. then proceed to dispose of the case where you can't see it, but knowing that it is indeed still there tears at your soul. You vow never to lay hands on it ever again. Depending on how far gone your mind has become, this can last for several months to only a few hours. Then the cycle repeats.
