Just trying out the Travel Journal to keep track of my playthroughs.
I've completed all of main series except duplicates (red&blue only played blue)
Now i'm into ROM HACKS.
I never use the same pokemon twice, so whenever i beat a game with one, i will never use it again unless it's a different evolution (think eevee family)
Now I just started Wally Version of Emerald, a neat looking hack. I can't use all of Wally's team because I've used all of those pokemon at some point in the past.
1 hr in, i still haven't encounter a pokemon i haven't used before.
Wish me luck, I will update if there is anything to update or if I remember this travel journal is a thing.
