Looks like I’m late to the party, but better late than never. Just wanted to give my two-cents regarding an inquiry about whether or not to play Pokémon Spork.
The beauty of fan-games made via RPG Maker is that you can do a lot of things in terms of eventing. You can make a extremely simple adventure (like Spork) or make it so complex that the decisions you chose could have an impact of the game’s true ending (like Reborn, Desolation, or Rejuvenation). Pokémon Spork seems to lean towards being a pretty relaxing adventure as if you are playing a regular Pokémon core-series games. There is no level caps regarding obedience from all Pokémon (though I recall traded Pokémon in core-series games can disobey if your Pokemon went over the level) and also no Field Effects (except from already established ones in the core series games such as Misty, Grassy, Electric, and Psychic), so you should have no problems going through this adventure.
To share an analogy, if there was a Pokémon game which is extremely similar to Pokemon Spork, I have to say that it’s on par with Gold/Silver/Crystal along with their remakes of HeartGold and SoulSilver. These are one of the few games where it contains 16 badges, and that’s because there’s two regions to explore (Kanto and Johto). Spork and other fan games has 18 badges to cover, so that’s not too far off. And as far as villainous team goes, I guess Team Portal would be the equivalent of either Team Yell or Team Skull since, I believe, they’re only slightly causing trouble, but not to the point where you see any type of destruction or majorly unethical actions that would affect the entire region.
So if there’s someone who absolutely never played Pokémon before and wanted to play a Pokémon fan-game, Pokemon Spork would definitely be the first choice of start your adventure. The A.I. Pokémon Teams are appropriately leveled so that it gives you an idea of when to grind, and luckily, there are lots of Pokémon Breeder with their team of Audinos using S.D. Attacks designed to Knock Out itself and give you massive EXP (though I still think Blissey gives far more EXP than Audino, I would have to experiment that). Some of the Pokémon’s movesets are somewhat optimized for major characters while most regular trainers have Pokémon whose learnset is based on what level they’re at, as it stores the four most recent level up moves if no other info is added in trainers.txt (tldr they’re not optimized). IVs can become 31/31/31/31/31/31 like Champion Cynthia from DPPt but no EVs are specifically assigned since the most Essentials can automatically set is 85/85/85/85/85/85 for a grand total of 510 EVs if the Pokémon is level 57 or more, so their stats are also unoptimized. As far as dialogue goes, I think some NPC made clear where to go next, so there isn’t a time where I get stuck on somewhere.
Oops, I was rambling into making a review of that fan game, but my point still stands that this would be the first fan game to play if you haven’t played any Pokémon game before or just fed up with intense difficulty Reborn and Rejuvenation provides (since they optimize everything). I see that you already have played those intense games, and I can see why you might not like it, and that’s okay. I know I have some of my stuff that I would either invest on or put it to the side. It’s also hard for me to recommending something because I don’t know what people exactly want. As for me, I enjoyed Pokémon Spork the moment I started playing it last year (July 2019), and it was extremely fun and enjoyable, to the point where I recorded 4 separate adventures on my YT, making some fan arts of Spork related characters, made one appreciation post, and (even extreme) made a side story related to Spork with the goal of making it as hard as possible (which I hope would be the most difficult side story in terms of team composition). And even to this present day, I still got work to do!
At the end of the day, ultimately, what matters the most is whether you are willing to enjoy your experience. Our insight and thoughts can only go as far.
