Vic Viper VS. the R-9
Gradius Vs. R-Type
Mortal Kombat Vs. Street Fighter
Lolo Vs. Solomon's Key
Well? (a hole in the ground usually filled with water)
These make sense as they are basically a match of two games from the same genre, the first matchup leads into the second matchup. This thread also smells like an alternative to polls to me. MGS PW and GoW COO have about as much in common as peanut butter and pickles.
Plus this thread literally has no meaning behind it, is it which do you like better, which is more overrated, which one is more balanced? Nope just a simple well, and since 4 days later we still don't know what this thread is for, I'm locking it.
