Oh, that's an idea. Hadn't considered something like that. I didn't think that kind of character switching was popular? But if players wouldn't revolt at the idea and it could be done well and it fit the game and story being told? Sure, if it works it works!
I just draw the line at Leaguers. A Superman game should be a Superman game. Characters under his umbrella like Kara and Conner and Mon-El? Absolutely, use them! I agree with you about the public not realizing how deep this well is (DC themselves don't acknowledge it half the time). But the last thing a Superman game needs is Leaguers edging in on the spotlight.
Convince Bethseda to make the game and you'll have millions of follower mods made by players anyway, and half of them will be the League. Other half will be Avengers. No point in the studio doing the work if the players will do it for free.
Lot of characters to work with too. Expected names like Kara, Conner, Steel, maybe Jon or Krypto. But you also got Gangbuster, Guardian, Alpha Centurion. Maxima. Valor. Super robots from the Fortress. Hell, Fortress controlled battle mechs! Lois and Jimmy, Maggie Sawyer, Emil Hamilton, Leo Quantum or whatever his name is from All-Star! Power Girl! Shay Veritas! Bizarro! Bibbo! Any of them could be a viable follower, or party member, or alt character or whatever, used right. Maybe the non-superhero followers like Bibbo and Lois/Jim provide blanket buffs instead of assisting in combat. If you have to contend with collateral damage, maybe they provide a speed boost to civilian NPC's leaving the area. Maybe they just cheer you on and provide a bonus to critical strike damage.
I was thinking of just having NPC followers you'd unlock in various ways, like finishing a mission chain or completing a feat or whatever. Maybe a small degree of customization (equipment slots or something). At most I was thinking of having more than one follower at a time (crazy, I know!
) But being able to play as multiple characters....I wouldn't necessarily be against it, though I'm selfish and don't want to share, even with his cousins, brothers, and kids.
