As I've mentioned before, I have a bad habit of abandoning video games when they get too difficult. Fortunately, since I mostly play role-playing games with save features, I can always pick them up again later on. Perhaps this won't be interesting to anyone but me, but here's a list of games where I've made it part of the way through:
Chrono Trigger - In the DS version, I've reached Masa and Mune, but I can't defeat them. I wonder if I should swap out Robo for Marle;
petie_s says that the Antipode spell that she and Lucca have works well.
Chrono Cross - It was a long time ago that I played this game, but I remember I couldn't make it through Fort Dragonia. Unfortunately, it's one of the few places in an RPG where you can't just retreat and get more supplies when you're ailing.
Dragon Quest IV - I've beaten the NES version, and I've made it up to Psaro the Manslayer in the DS version, but I haven't defeated him yet.
DQ5 - Just started on this one, but it's pretty cool so far. I've reached the fairy kingdom.
DQ7 - The farthest I ever made it was that really obnoxious 3-D maze.
Final Fantasy II - I've actually finished the main game, but I haven't gotten anywhere in the Rebirth of Soul thing in the Game Boy Advance version. I'll probably try it again at some point, but it's not really a high priority, since I already won the game as it originally stood.
FF3 - Just started this one, actually.
FF4 - From what I remember, I made it through the Tower of Bab-il, and am now facing the Cave of Eblan. I'm somewhere around there, anyway.
FF5 - Made it up to Exdeath. Beat Exdeath's first form. Had my ass kicked by Neo Exdeath. Forced to write in sentence fragments.
FF7 - This was my brother's game, and I doubt my save is still on the memory card (if said memory card even exists anymore), so I can't pick up where I left off. From what I can remember, though, I made it up to the space rocket part.
FF9 - Another one of my brother's games, I barely got anywhere in this one, and died in the first cave. It probably wouldn't have too difficult to try again, though, considering that you seemed to increase in level every time you tripped over a rock.
Mario and Luigi: Superstar Saga - I think I'm fairly close to the end, but I'm unable to beat Roy Koopa. And since this is an action RPG, it takes a little more time to get used to it after not having played it for a while.
Paper Mario - I'm in the forest where Tubba Blubba lives. I don't think that game ever became too difficult; it's just that I don't get too many chances to play the Nintendo 64.
Phantasy Star II - I haven't made it very far, but I'm confused as to what I'm supposed to do next. I think I even tried looking it up in a walkthrough, but it was still confusing.
