I played DoD a lot before switching to Red Orchestra as a mod for ut2004.
Day of Defeat is a great game, but Red Orchestra is simply different!
Its like a comparison of Counter Strike with Operation Flashpoint, except that RO focuses a lot more on the infantry-fights than operation flashpoint.
Day of Defeat vs Red Orchestra isnt about better or worse, its about taste. I still love to play counter strike once in a while, it has it own good points.
I also loved call of duty (although i only played the single player), it had great athmosphere and a nice balance of arcade-like gameplay with a touch of realism and historical aspects.
Day of Defeat:
- a lot of quick action, quick movement.
- The most important thing is your aiming and your reaction time, probably also map knowledge
- weapons arent really realistic, but well balanced (at least in the mod times, havent played source)
- although the graphics were rather good and the szenario is right, dod never aimed for as much immersion as RO
- the maps in DoD are rather small and clearly arranged: you know the "hot spots" and where to exspect your enemy, since the routes to take are more defined
- the learning curve isnt as harsh, since the gameplay is more like a typical fps
Red Orchestra:
- slow movement, all in all much slower gamepace: the game rewards a care- and thoughtfull player who uses the terrain to his advantage and takes cover
- rather realistic weapon behaviour leads to realistic weapon usage: run'n'gun-rambos are WAY less effective and are more like suicide actions
- less focus on pure aiming and reaction time: spotting the enemy first, flanking and suprising your enemy and taking time for a well aimed first shot leads to success, quick reaction time and instant-aiming is less important: finally a game where brain beats reaction time!
- the realistic game athmosphere and the more difficult aiming creates a very tense feeling and makes a won firefight so much more rewarding than just another frag
- since the different gameplay requires to change your behaviour ingame (compared to "arcade-like" fps) the learning curve can be pretty hard, but once you start to "think Red Orchestra" the game developes its full potential and becomes (in my humble opinion) a revolution in terms of gameplay in first person shooters
- the community in RO is a lot more social than in other games (at least in mod times) since the game appeals more to a grown up person: there were way fewer idiots, flamers, team-killers and other kinds of that public-fps-mob!
