Yeah Lilligant is pretty game breaking, no doubt about it. I successfully swept Shade, Kiki, Serra, Noel, Luna, Samson, Terra, and even Ciel with it, the thing is terrifying. Honestly Ciel stood less chance than most thanks to the big top arena breaking Lilligant even harder than it normally is. It completely trivializes any boss battle after Shelly that isn't either an overlevelled pokemon or a double battle. I guess the difference between Lilligant and Gyarados is that people used Gyarados while people don't use Lilligant, hence it remains in the early game.
Well past bloomin' time if you ask me but you already know that. Still, it's good news.
You talkin' about new items that you added a while ago in the E16 development period or new items that you added in previous episodes? Obviously I can't help you with the former, and I still can't help you with the latter because if you think I know anything about where stuff is in this game that I haven't played in who knows how long you're joking.
Maybe Route 1? I spent a whole day there the first time I played through this game because I was recovering from surgery at the time so I couldn't really get out of bed and my first run of Reborn was engaging enough to keep me entertained. I remember the reason I was there for so long was I was looking for Heracross (and it turned out to be in the very last place I looked) but even just riding around on Tauros was something I thought was rad. So yeah, I've got fond memories of Route 1 and I'll probably go back to check out if it's changed.
