My backlog is so ridiculous....there's no point in posting it all. I'll just say lately, I've been working on playing thru all the Spidermen games from the PS1 on up(though, I actually played the first DC version of Spiderman 1). IIRC, I started with Spiderman 1 & 2 Enter Electro, then went up to Ultimate Spiderman, then played the 3 movie games in order for PS2 with SM 3 on PS3(I hear SM3 on PS2 is a different game), then Friend or Foe, Web of Shadows, & am currently on Shattered Dimensions, which is flippin' awesome! I'm almost done with that, & will move onto Edge of Time, & eventually when Amazing Spiderman drops to $20 or less, I'll pick that one up.
I also went on a barrage of playing my Transformer games, starting War for Cybertron, then Armada on PS2, followed by the 3 movie games on PS3(man, the first movie game is terrrrrrrrrrrible!). I got Fall of Cybertron, might play that before playing SM Edge of Time. I don't think I'll ever be able to beat the first Beast Wars game, it's just too junky & difficult. I already had beaten BW Transmetals for PS1 BITD, but found the N64 game to be quite difficult. I also have the Jp only Tatakei, but, it's fairly bland in the gameplay department, though it's awesome that it's almost completely in english, & even calls the bot's by their US names(ie: Optimus Prime instead of Convoy, Jazz instead of Meister, Ravage instead of Jaguar, etc.). There's an old BW GBC game, but I've never been able to track it down for cheap, so, oh well. There's also a Transformers Prime game coming to DS, 3DS, & Wii(& possibly the Wii U). No matter what, I'll probably hold off till it's cheap, & get it on Wii or Wii U.
I do wish to play thru all the localised Growlanser games, as well as the Wild Arms(only beat 1, 4, & Alter Code F). These are the main game series coming to mind ATM. Oh, I still need to play Arkham Asylum, & need to pick up Arkham City. Also, I have alot of Final Fantasy's that I've never played. The ones I've beaten are 1 on PSP, 4 on PSP, 5 on PS1, 7 PS1(was actually my first FF), 8, 10...& I think that's it. I will eventually beat 2 on PSP, 3 on PSP, 6 on SNES(or PS1 or maybe something else in the future), 9, 12, 13 PS3, 13-2 PS3, 13 VS. PS3, 0...assuming it ever gets an english translation. I have beaten Dirge of Ceberus & Crisis Core. I would like them to bring over Before Crisis, hopefully on the Vita, though they talked about bringing it to 3DS. I have no desire to beat 10-2, it just....I can't get into it. Heh, same goes for 11 but for different reasons. I would like to eventually beat Tactics on PSP, as well as the 2 Dissidia games.
