Makes sense, of course. I'd much rather just play CD than the Gaiden games, even if the extra books aren't too interesting (in my opinion) except for the shadow battle in Book 3. I only ask because of these very specific circumstances. Oh well. I don't even know yet if he'll want to play the other ones, but I thought I'd ask in advance. Besides, with how much I've been going on about how much better SF2 is than the first game, he may just want to jump to that instead. I thought it would be fun though to play them chronologically, since he's never played any of them before.
It has actually been a lot of fun letting him be mostly in control of things. Letting him take the lead in battles (with me giving the occasional important warning, such as making sure Marionette didn't utterly obliterate us as he did the very first time I fought him because of all the surprise, bullshit boss abilities the game suddenly throws at you) has resulted in playing out some fights in ways I never have before. Watching him decide which party members for us to use has also been neat since he knows very little about their potential aside from a few vague hints I've dropped, and has resulted in a rather interesting party; such as keeping Ken.
Talking about that reminds me that I've been wondering whether or not to tell him about the wooden plank in Shining Force 2, or leave it up to him to figure it out. It might be fun watching him experience the dread of figuring out how to use it for himself.
