>>29679216I'm going to assume you're a newfag and this isn't bait.
ORAS is Omega Ruby and Alpha Sapphire. It is four words (ignoring the "and"). The only other games with four-letter abbreviations are FRLG (Fire Red and Leaf Green, four words if you exclude "and") and HGSS (Heart Gold and Soul Silver)
SM is Sun and Moon. Two words. This matches RB, GS, RS, DP, BW, and XY. If there's a third version like Eclipse, it will become SME, or whatever the third version's name is. This matches RBY, GSC, and RSE.
Everything above is one letter in the abbreviation for each word that is is abbreviating, sans the word "and." The only set of games that break off from this rule are DPPt, and this is because Pearl and Platinum start with the same letter, so Platinum is denoted as Pt to avoid confusing when discussing Gen 4 games.
The only people who use "SuMo" other than shitposters are redditors, who adopted the phrase because they were afraid of children Googling "SM" and finding sadomasochism. If you use "SuMo" either your post is disregarded as a shitpost or you are disregarded as a redditor who hasn't adapted to the board.
Don't use "SuMo."
