While I generally actually enjoy grinding in games, the grinding involved in the Pokémon metagame is just so RNG (or attempted RNG manipulation) dependent that it's insane to even think about for me.
EDIT: OMG 100th page hi everyone.
I've personally always loved Custom Robo Arena for the DS. Plot was above average, gameplay was fun, and the concept was amazing. Definitely in my top five, and yet only the most hipster of my friends seem to know about it.
A game is a lot like pasta.
Pasta is technically edible after a few minutes of boiling, if a bit chewy, not very nice.
If you cook it with patience, perhaps with some oil, at a rolling boil in salted water, drain it and add a nice sauce with some roasted vegetables, and present it on a beautiful plate, with beautiful cutlery on a beautiful table in a beautiful restaurant with beautiful sounds and scents; VERY NICE.
