I *tried* to play it for about two weeks when it first came out. I, like many others, feel like the game can be too buggy in some situations, but that honestly isn't the reason why I stopped playing. I realized that I wasn't interested at all in the game, because it was so different from what I like about video games in general:
>The game requires you to walk. While I like going on walks for an hour or so on occasion, it's not something I feel inclined to do so often as I would want to play a game.
>Outside of catching and gym battles, there's fucking NOTHING to do. Even with the future update adding trading (which definitely should have been in the game at launch), that wouldn't be enough to keep my interest. You may think, "But isn't that the same in main series Pokemon games?" Not quite, for me, anyway. This leads into the number one thing that I don't like about GO...
>The game takes place in the real world, because it's VR. I didn't expect playing a game without its own world to get old so fast. But then I realized it's the biggest reason why I play games. I love seeing what fictional worlds I can explore, with different people, technological advancements, and impossible environments and landmarks. I like the world I live in, but it makes for a boring as shit game.
Keep in mind, this is why I don't like the game, not why I think it's bad. I still haven't made up my mind on whether I think GO is ultimately a bad game in my eyes. But it should be obvious that the first and third arguments of mine are because of the game being a mobile game you play by walking around, not because of the game's inherent design. The second point, though, IS a legitimate complaint I have against Pokemon GO itself. I have no idea what more they could do for gameplay besides trading, but as someone who prefers to play games alone, the experience is barebones, which I suppose is my fault for expecting something more.
