Ended up going back and just playing some more of Genesis mini 2. Man these games are all pretty tough or slow. Not sure if there's any easy casual stuff on this group.
I never played Treasure's Alien Soldier before. Don't really get the controls. Couldn't beat the first boss.
Never played Viewpoint before, not a fan of 1 hit death = restart entire stage, especially with the weird isometric view for dodging bullets and large hitbox
Langrisser 1/Warsong is actually kind of neat, but sitting for 3-4 mins while the enemy takes their turn is zzzzz
Shining Force CD gameplay is kind of neat, but it's way too talky
Shining in the Darkness has nice art, but the dungeon crawling is kinda zzz
All these FMV SegaCD games are terrible. Mansion of Hidden Souls could be good except can barely see shit and it runs so slow.
Ristar seems kind of neat. Never played it before. Like the grab mechanics.
Elevator Action 2 is still solid though pretty sure I've played better versions.
Final Fight CD has nice music and voice but I don't like the more bland lack of colors compared to the SNES/GBA versions.
Vectorman 2 controls pretty well but the stages seem kinda unfun
Puyo Puyo in this is 2p only? Otherwise just endless practice mode?
Virtua Racing is boring compared to the Saturn version and various ports over the last two decades.
That being said, I do greatly respect the sprite scaling used in the emulation as the games look great. I wish the PS1 classic looked like this visually. Hopefully with the autobleem it'll look closer to this for 2d stuff Wild Arms.
