It is also possible that the gem system will take place in a separate mode within the game entirely. The article does confirm that gems will directly impact the moves of each character and their specific timing, allowing "character customization". Ono states that more details of the system will be revealed at New York Comic Con.

Capcom's upcoming crossover fighter Street Fighter X Tekken is taking the customisation options one step further, and will apparently allow players to change character moves and even timing. Street Fighter X Tekken producer Yoshinori Ono confirmed to GameSpot today that the gem system—which has been hinted at in previous weeks—will go further than simple costume changes, and will let players tweak individual characters and how they actually play. Ono said traditionally with fighters, characters are exactly the same, with the only thing separating players of the same skill being the ability to read a competitor (and a little luck). The gem system will drastically change this, letting players customise their characters so they are no longer straight clones, Ono said. While Ono didn't divulge too many details, he did hint that the gem system will allow players to change moves and timing for characters. No other detail—such as what the process is for changing, how often you can do it, and more—were outlined, though Ono-san did say more detail would be forthcoming at the New York Comic Con. Keep it tuned to GameSpot for more details on the gem system soon.
