It seem like the game is pretty solid and the only complain I ever see is just graphic.
Yeah, I'd say even the graphics can look nice at times being that this is clearly based on the BotW engine and/or some of its assets. The pop-in is killer though, as is the view distance and distant texture detail. And of course FPS still feels like it's in the 20-25 range most of the time despite all that. I look forward to when we can mod this game to the point of changing the in-engine settings.
When it comes to gameplay, it is undoubtedly the best single-player Pokemon experience released in a long, long time. Now granted, that's not too high a bar to clear, but even compared to other AAA games, and more specifically open-world games, I'd still rate it quite favorably. Somewhere in the 8.5-9 range, whereas I'd give Sword and Shield a 6.5 at best. What makes it so much better are a few things: the way the economy works, the speed at which most actions/animations are performed in combat and out, and the battle difficulty. On that latter point: that's correct, battles are more difficult overall despite having a lot fewer trainer battles in the game (my one gripe other than graphics). Wild Pokemon have knocked out one of my own with a single normal effectiveness move when they were only 1-2 levels higher; not to mention how much stronger alphas are on top of that.
I had canceled my pre-order previously, but I'm now seriously considering picking up a copy at launch. If nothing else, to try to help encourage the direction they've taken with this game.
