i was never interested in playing tetramaster, i didnt even bother looking at it.
but adding mini games in FFXIV will be great.
for example they could make tetramaster inside FFXI, you can buy the "collectible cards" from vendor, and you go hunt the ten of clubs/robots thing to get the other cards and then start the mini game with other adventurers.
or adding minigames only during the festivals/events, like you see lots of game counters when there is a fair or something.
minigames could be like, kabobs eating contest, you compete with up to 5 ppl at the same time, ... u get the idea
or a marathon, u have to run naked, nothing equipped, run from limsa lominsa to Ul'dah, no transportation nor any abilities can be used nor spells can be casted, just pure running. but then everyone runs in the same speed, how can you win? by knowing the short cut and knowing your way. there will be chests on the way, u can open and use "items".. like you bind the person u see in sight, instant flee, dig a hole and set a trap on the ground to get the person behind you, you blind the lead runner so his screen goes black.... ok you get the point, it's just like Mario kart lol, but then im not including monsters attack, that will make high "level" doesnt have the advantages
or put us in a dungeon, split into two teams where we will have to find 5 flags of our team's color first to win.
