I’d love to see a modern take on Cannon Fodder, as well as another entry in the Desert/Urban/Soviet/Nuclear Strike series.
Lastly, there was a very fun demo/mod to Sensible Soccer for the Amiga that set the match between UK and Germany, and replaced the ball with a bomb that would periodically explode and eliminate any nearby players. I’d live to see a modern-day version of this, honestly - just some goofy fun!
..and yes, I am fully aware of just how old this makes me all sound.
For a modern Desert Strike check out Cleared Hot on Steam. It's not out yet but it looks promising and it's by a guy who wanted something like Desert Strike. Funnily enough it came up in a similar thread on Reddit a while back and I added it to my wishlist there and then.
