Differences between Gen 2 and 6 mechanics?

Question

I have recently been playing my copy of Crystal and have been wondering about the differences in battling , EVs, if moves do the opposite of what they are supposed to do (Focus Energy back in gen 1) or are broken (like Wrap), etc. compared to Gen 6 and its style of battling.

Comments

mega evolution and fairy type immediately come to mind. As well as ghost and dark not being very effective against steel in gen 2

---

Physical/Special split as well. Critical hits are no longer based on Speed.

---

Crits were only based on speed in Gen 1.

The list would be impossibly long.

Answer 1

• Horde Battles
• The number of boxes available was increased
• Ability to move multiple Pokemon in boxes

• The ability for the player to walk in an 8 directional grid as opposed to the 4 directional grid
• Pokemon Amie and Super Training

• You can actually see some stuff without Flash, earlier it was just black

• Pokedex was upgraded in many levels
• Ribbons
• Different sprites for gender-differentiated Pokemon
• Eggs hatch at Level 1 instead of 5

Battle Spot, GTS, Wonder Trade. Basically improved trading.

I dunno if I should include that because it's not really an in-game mechanic...
Screw it, thanks :3

Ehhh, no problem buddy ;D

Thanks, nice list

Added a bit more that I remembered while I was asleep :P
And no problem!
