you're assuming that others play the same games, use the same key combinations, and have the same keyboards as you.
what you should have said is 'long and short is, i don't need nkro to play today's games'.
nkro isn't necessary for gaming, but it does guarantee that you'll never have to worry about key blocking because all key combinations work.
That's why I prefaced it with what games I play, what key combos I use.
Your mileage may vary, if you play different games, or if you use different key combos, or if you play at a whole different level of gaming than I do, you may find NKRO useful.
Anything I ever post is only the opinion of myself. Any advice I give is only what I feel to be helpful to others here.
I have had NKRO filcos, non NKRO filcos, non NKRO Chicony and Dell AT101, non NKRO Cherry g86 board, a ton of rubber dome boards. This is my prior experience. The games I play are CS:S, TF2, Warcraft 3, starcraft, L4d2.
If you are playing other games or using other applications in the future that require multiple simltaneous keypressess, your experience may be different.
Just know that if a game maker releases a game which requires a keyboard with NKRO to play the game, the majority of the world with standard keyboards will not be able to play it well, and will probably complain.
I would also like a good example of a game that really benefits from NKRO keyboard. Multiplayer Star Control comes to mind, but of course, that is a little on the old side.
