Yeah. There are some games that are direct sequels, but a lot of the games have little bits of in-jokes and references to one another.
>Kaworu from Evangelion alludes to SRW MX during some dialogue in SRW Alpha 3
>Go Saotome in SRW 30 is heavily implied to be the same Go from the SRW Z games, plus Advent also shows up as a hidden boss
>Getting your memories of a past life is a big plot point in a lot of games. Said memories tend to just be memories of other SRW games
There's more, but that's just off the top of my head.

I was honestly expecting a reveal that Y's Knight and The Second were going to be 30's Anti and Ansirous II. I'm not sure how much they'll play around with Gridman Universe's lore.
