But why not using directly Magic modified card/rules (as it's where the "Tragic" come from) ?
That would be nice, too bad this "mini"-game will consume too much time to implement, if only it'll have only few cards but then it'll be boring.
Even PC
MTG Shandalar is a game itself lacks a lot content and it's boring to play after 1-2 days.
About Arcomage, I'm playing Arcomage with other people almost everyday in a browser game based on heroes5, of course it requires tactic and experience, but still, there's too much randomness, like in whole FOnline >_>
After playing some days in Arcomage you'll know what cards enemy have, and when each card will come (if you're playing with 1 deck), so if both players know that game well, it's pure random. It's easier and faster just to roll dice and you win on 1-3 and enemy wins on 4-6, I think that game requires less time to implement and can be played even now with dices.
+How MTG or Arcomage will be implemented in FOnline, too much work for interface. Really much work. Easier will be make
Pazaak from Star Wars, if each player will have a deck with different cards which he can collect/trade, base deck will have only +1/+2/+3/+4/+5 cards, you can buy - and -/+ etc. this will be easier.
Not Arcomage nor Pazaak are from fallout, and making MTG will require too much work (btw Arcomage too).
