i am a perfectionist in gaming. I am always beating the game in way like i am attempting to platin or 100% it and then i still quite after i beat it lol

I would say i have addictive personality but not OCD. Lot of online games games these days are made with a focus of targeting the vulnerabilities of their user base. I know most Blizzard games are like for good or bad. They keep me coming back to Hearthstone on a daily basis, if not at least 4-5 times a week.

As Joka mentioned. Destiny uses similar daily quests to get people coming in everyday. One of the interesting things that came out of that flawed game recently is that. They improved the chances of getting better drops with the Taken King. You'd think that people would be happy and will be playing the game more. On the contrary, the interest in game dropped more as people have to grind less.

So, i guess the lesson is people don't deserve nice things. Game was more successful in terms of retaining userbase when it was utterly exploitative.

Not really, on the contrary I usually do not finish most of my games and my issue is trying to finish them so I don't feel my purchase went to waste.

I do, but only with games I truly like. I don't feel the desire of finishing/completing games I don't enjoy playing.

I've learned to just let go and it has made gaming much more enjoyable. It is not only about collectibles, achievements/trophys, side quests, main quests, etc...but I don't stress anymore about playing and experiencing every game I'm highly interested.

I answer yes to that 2nd question, so I guess fall into having OCD, haha. Sony gets me with their trophy system. To solve it, well, people know how I do that... >.>;

I do have OCD. Been diagnosed with it since I was 6 not just for games though. But when it comes to games I tend to buy them obsessively

I used to be a lot worse...but I think playing more games at once helped me figure out what to prioritize. Though if I really like a game, I'll still unlock everything I can. For example, I don't consider a Zelda game completed until I have full heart capacity and max storage for all my weapons. But games with multiple endings rarely have me playing alternate routes till much later.

I usually don't bother with trophies though...unless it feels like a natural reward for completing the game. I recently beat Tales of Xillia for example...and one of the trophies was to use a certain move like 1000 times. No thanks.

Also Im OCD in how games are stored XD if I have a system with physical and digital downloads it drives me insane... part of why I LOVE the PSP Go, it forces me to only have digital.
