>>55464579HeartGold was $130. Retro game stores around here list it at $150-$200.
Black 2 was $120. Similar listing price at local stores.
Diamond and Pearl were $40 each. Even with the Pretendo network trading, I still needed another for Manaphy egg soft resetting. I already own Platinum.
Ruby was $80. This one had Deoxys and Jirachi, but they were badly hacked in. I needed an additional Hoenn game for berry blending. I already own Sapphire.
Emerald was $180, purchased last year. Save for the Battle Frontier I've completed the game, excellent. I need to replace the battery in it again, I think I installed an almost-dead one and it won't sync with my FireRed and LeafGreen for the wireless minigames.
Black, Alpha Sapphire, Moon, and Ultra Sun were $120 in total. Got them in a combo discount at a local retro game store.
So $710 in total. Money I can make again, but games I now don't have to hunt for anymore.
