In EU I can Let's Play a mission in under 45 minutes. I actually do bother with a full move sometimes, which I doubt I would have ever done in UFO Defense.
Technicly you KNOW there won't be an enemy in certain areas and they won't attack you while you are moving. (they will do their little animations, get a free move, flank you and THEN kill you)
Which is one of the things I miss from X-Com. You could run, spot an enemy and immeditely duck for cover, back up or whatever. (assuming the enemy didn't reaction-fire you dead) Of course, X-com has many, many DERP moments and flaws of it's own.
To this day I consider Jagged Alliance 2 the pinnacle of squad-based tactical shooters.
Technicly real-time untill enemy contact? Great, speeds the game up!
Learn-by-doing system that doesnt' suck? Check
Soldiers with personality? Double check
Tons and tons and TONS of options and ways you can play? quadripple check!
