Street Fighter combos, Street Fighter combos, Street Fighter combos.
Do you write for Polygon or the like? Seriously, beyond the fact that buttons are pushed and things are called combos there is no similarity whatsoever between these games unless your skill levels and general reflexes are so painfully low that multiple inputs in <1 second are the same as a single button or even multiple sets of those <1 second inputs within 2-3 seconds are the same as pushing 3-5 buttons over 6 seconds tops.
If you really have that bad of a reaction time, you should probably stick to turn based games.
