I'm 100% that it will be # for at least 5 years.
Here are my reasons on why this probably looks like it's better than the rest of the mmos I've played and thank god I didn't invest more time in those. Good things come for those who wait.
1) Overworld. Just by walking around the overworld sounds amazing. A very good job with the best overworld from any rom hack, mmo, rpg maker pokemon game.
2) 6th gen for full pvp experience. Not that lack of mechanics in pvping from gen 1-3. Obviusly up to date pokemon strategies.
3) The music isn't something that different but it sounds way more high quality than the official.
4) Nostalgia and added side quests. It keeps it fresh and nostalgic at the same time.
5) Your journey at friend's journey. I always like to keep in touch with something with our progress and how we can help each other out.
6) the battle scene gui will get better but I have no doubt it will look awesome with updated sprites and move animations.
7) how tough are ya? You think you've learn from beating hoenn's league with one rayquaza?
8) Basically everything that's good about pokemon.
So I'm hoping to last some years with this and see where it goes. The only thing I haven't seen is the economy and how grindish it is but I'll see. Only bugs could only ruin the exp.
