Some questions
1. Why the 'only 2 coins if oppositions is dead' rule?
2. Would the trophies do anything or would they simply be collectibles?
3. Some abilities would be kinda cool. Maybe a choice, or a random ability is given to each player at the start?
Gimme some time and I'm sure I can come up with some new items if you want
Also, it would be nice if the games could last a fair amount of time (I don't know how long this round will last yet obv) so as to give lots of time to strategise and gain enough money to buy high end gear in the shop. Stuff like the ring that halves shop prices is good because it introduces a bit of thought into the purchases, i.e 'Do I buy this awesome sword??' 'Or do I save a little more money and buy the cost-cutting ring??'
Edit - What do you mean by live?
