This is an exciting project and I have already been eyeing it and wanting a vial.
The two main reasons are:
Development - the team are reputable and rug pull is not likely. Progress on the game is steady. The tidbits that are revealed look great! And the team is transparent in their dealings and such!
Community - this one kind of goes hand in hand with development, in a way. I'm not the only one excited about this future game! There's a vast and interactive community that are also eagerly supporting the project! The dev team also has to keep up in terms of scaling, community events, and like I mentioned earlier transparency.
Notable mention: the artwork looks so cool, inspiring loyal fans to share their own renditions! This melds together the community and the team (yes the artists, too!)
I've heard of other similar projects over the years (that still exist) and even some much older ones that feel like their progress has stagnated or turned in a different direction.
I am vaguely familiar with the Pokemon games, only having played one of the oldest iterations and a bootleg version at that. But I still loved the concept and the RPG genre in general!
I'm extremely excited to play Holozing, when it is ready. For me, it will be like the spiritual successor of that very first game I played.
