For as rather complex as the SEGA controller can be (fun too), Virtual on has always had a soft spot in my nostalgia. The first and second games were fantastic, offering a rich pure arcade combat style that is fast paced and tournament entailed.
Oratorio Tangram is my all time favorite in the series, not just for the mecha edit mode, but also having a decent range of stages and mecha to choose from. So far only the first Virtual on was ever ported for PC, and Oratorio was simply either arcade or console ports. If there's a chance that SEGA can released this game, even in that Virtual on collection that was for PS4/PS5, that would make a lot of people happy.
