Are we talking about good ol' first generation Game Boy/Game Boy Color games? :>
If so I have two of them:
Dragon Quest Monsters / Dragon Warrior Monsters
1 not 2 (I dunno about 2... might be awesome, might even suck, but I don't own it xD)
INFO
You might call this a pokemon clone which it is not exactly... The idea to catch monster and let them fight for you is the same but that is all about it. The game has
- its own storyline (simple but entertaining),
- monsters and other characters with funny personalities,
- up to 3 monsters fighting on each side during battle mode,
- the possibillity to breed monsters and combine different species to create a new one (there are even secret combinations that give birth to the special boss monsters)
- many, many abilities that the children can inherit from their parents
- high replay value and it takes long time to beat
Links Awakening
INFO
Ouf what should I say? Epic Zelda game! Fun to play still after years again, again and again... :D
