This is a major topic for fangame discussion. What do you think about putting Fakemon in games? How do you prefer them to be implemented? Do you think they should be implemented? How can mixing them with the canon effect your experience? Discuss!
Personally i'm 100% for Fakemon across the board, new Pokemon add more to the Fan Game for me, but they have to be done properly, Poorly Made or Poor Performing Fakemon is a deal breaker as far as i'm concerned.
so since my Fan Game includes 151 Fakemon to be implemented, i am not going to leave them half-baked, they will have proper sprites, animations, etc.
Fakemon, though they are completely optional and not required, allow a dev to mold their region how they see fit, and create dificulty and level curves with such precision that isn't entirely possible with regular pokemon
While you can adjust regular pokemon (and it's better when you do!) If you change official pokemon a bit too much, it becomes a little confusing for players who are used to a certain poekmon's stats and viability, where as if you have a totally new pokemon, they learn it on their own, or read up on it.
Another advantage you get from Fakemon, is giving a new sense of adventure - a major selling point of PEG's demo was a familiar experience but a brand new adventure, a rekindling of what made you love poekmon from the beginning!
The way Nuclear Omega handled Fakemon in his game was also great, he created a whole new meta and was able to create type combos and battle strategies that you could only dream of.
Utilizing fakemon in these ways, rather than as a novelty is definitely the way to go. Don't have Fakemon just to have them, use them for a reason.
