Ghostbusters on NES (I think a very similar game came out on other contemporary systems). While the Mega Drive ghostbusters game was hard but it was worth playing, I don't understand what they were thinking with this one. (What were they thinking?) For people who have played it, back then or now, do you think it has any redeeming qualities? The only thing I can think of is the AVGN episode that came out of it.
I ended up cracking my copy of it (which was pirated anyway) and gave myself a ton of money at the start as well. Fun game for kid me, not really a classic.
I also cracked SimCity and 688 Attack Sub but I had legit copies of those, I just hated keeping track of an extra piece of paper to play them.
