Imagine this with a bit more tweaking + the lighting and particle effects. To re-iterate, the final product will have the red beam + other particle and lighting effects, but this animation demonstration doesn't have them included.
Other than that, here's a quick list of features that are in/will soon be in.
Craftable Pokeballs (of different varieties), including the growing and use of apricots.
Pokemon based on biomes in the game
Flying Pokemon, which you can ride (tho most server turn this off, I think? Mostly because a lot of them make use of jump puzzles and being able to fly your Pokemon up to the finish point is kinda eh).
Regular battle system + Double battle + other battle types being added soon
Custom naming of Pokemon
You can send out your Pokemon to walk with you
Pokemon PC Storage
Various other items from the Pokemon games (including the running shoes I mentioned)
Often times 100+ people playing on the same server and in the same region as you
+Dozens of other "sandbox" features, that the normal games don't/can't have. Such as housing.
Edit: Also, in case this is confusing, I'm NOT trying to convince any of you to play the game. So no reason to go out of your way to assure me you still wouldn't play it. You've got nothing to prove here.
