-I don't think Cogita is that old. Even if she's immortal like the theory goes, she only looks to physically be in her mid to late 40s. On top of that, she's modeled and animated like the younger adults, not the seniors. So it's always bizarre to me to see people saying that she's Volo's grandmother (for that matter I don't think they're closely related either. Distantly related sure since they're of the same bloodline, but not closely).
-Legends looks dated, not bad. Saying "it looks like a PS2 game" isn't an insult and shouldn't be seen as one. There were some very nice looking games on the PS2. Heck, it's probably got better looking games than the PS3, overall, though that's more of an unpopular gaming opinion.
-BDSP were lacking but they also weren't bad. They were just DP But Again, and DP were good games. They could have been more, but they were never promised as more, and people calling them bad over something that was never promised is ridiculous.
