I few months ago I asked some dudes about what Front Mission I should play first. Everyone had an opinion, but most say to start with Front Mission 3, a solid game from the sound of it.
I just started teh game, of course, but I'm enjoying it. I bought the PS one game to ripped my own BIN file to play on my Duckstation. I think it looks pretty nice. As with most early games the ability to upscale the game depend on what type off asset is being displayed. If you know that game I cna say that the "Network" screen where you use the Interbet and read email get no graphical uplift, but everything else does. The in-engine cutscenes look great and the battle maps where you move & fight with look very good. On the 'battle screen' the Wanzers look especially nice and cutscrense between batlles - very nice.
Some the descriptive 'choices' in the game for characters are...very 90s. I'm not sure you can call women that word anymore...or you shouldn't... it's a life-style.
