Well done. That looks fantastic
I love this particular roster, and like many others that have posted before me in this thread, the prospect of playing through a Dawn of X/Powers of X scenario using the Legends game engine would be perfect as far as I'm concerned.
Other posters might disagree with me on my next point, but if they did a third Legends game, I'd like to see the developers actively encourage you to play with a broad range of characters, as opposed to just levelling up a select few i.e. have certain sections of the main plot restrict your choice of characters to just the X-Force or Marauder's roster for example, with all characters becoming available for the main parts of the plot.
Also, I think that it would be pretty cool to have certain levels where the field team is increased to 6 or possibly eight characters. I really enjoyed battling Sentinels in the original game. However, even back then, I couldn't help thinking how much cooler it would be if you had a bigger team swarming the enemy and felling them in multiple skirmishes dotted across the screen. That would be top of my wish list for a sequel.
Probably fanciful thinking to expect a revival of the Legend's franchise though...
