I started playing this game a few days ago - I'm having a lot of fun! I really like the format, the level of effort put into this, and the options available. I have a few suggestions/things I noticed, though:
-A notification when someone joins your quickplay/career game. I mainly am playing classic right now, which doesn't start as quickly as standard, so sometimes I'm waiting 5-10 minutes for a game. If I start doing other things, eventually someone will join when I forget that I have TCGone up and it won't start after a time. Which brings me to Point 2...
-When the game starts, if I don't click the "okay" button before the starting hand appears, I won't be able to pick a base Pokemon and thus the game has to end. I don't know if that's intentional to weed out afk people or if it's just something specific to Firefox, though.
-It'd be cool to have the FireRed through whatever the Diamond/Pearl sets are. I understand it's a lot of work, but it seems like a odd hole. I admit I'm biased here because after I stopped playing, I started playing again at Hidden Legends and FireRed, Deoxys, etc. were the sets I remember fondly. I don't really care much about Diamond/Pearl because I stopped at unseen forces or w/e it was
Maybe there isn't demand for these sets? (end monologue here)
-Being able to set up private quick-play/career matches with friends, and being able to enable/disable spectators. The second part isn't as big of a deal, but when I'm trying to play with a friend it's sad when someone else joins the game I set up and I have to tell them they can't play. This is a relatively minor issue, as the playerbase is kind of small and almost all the people I've seen have been cool, but it'd be a nice thing to be able to do.
Again, TCG one is a great website and I'm enjoying it. Certainly a step up from just playing the Game Boy Color games
. Those are just some things I've noticed/thought of. Thanks for keeping it up, and best of luck in any changes!
