OK so I"m way behind here, but FWIW I have a few limited opinions:
LOCATION
European Tourneys - Germany has a mega market to plumb into, but laws effectively ban cash prizes. Their turnieres advertise hardware as prizes, but obviously on the day you get cash equivalent. The juice on their competitions is astronomical. I don"t know if Berlin is any different to the rest of the country though...but my point is that there is HUGE potential to be tapped into there - and it will only get bigger as Pius Heinz leads the WSOP ME.
Holland is another location, though local regulations prevent use of Holland Casinos by 3rd parties. TBH they"re all a bit small anyway.
Belgium appears to be a market Pokerstars are working massively on opening up. TBH alot of their casino"s have been a bit slow in take up and in the past they have had slightly odd tournament structures - but I"m guessing as they get dragged into the mainstream this is changing.
My point is that its easy to cross borders in the EU - and many players do every night of the week. Go to Belgium/Holland and their casino"s are rammed with German players. I believe that Belgium is a very worthy candidate for investigation - as not only can you pull in the locals - but its also very easy to get the Dutch and (more importantly?) the Germans and French. Spa for one is very easy to get to for all 3 nationalities and absolutely gorgeous. Oh and Belgian beer is the best in the world bar none ;-)
SITE
I"ve found it difficult getting over for APAT from abroad for the last few years - but the one big turn off for me keeping involved online has been the choice of sponsor/software provider.
On 2 or 3 occasions I have looked at the sponsor and immediately thought uh-uh. Not playing there - as everyone knows which sites crash, have poor software, provide poor service etc. I"m sure there are plenty more players out there that think the same.
Stars was never ever going to be surpassed - and that season was an amazing experience for the online tourneys and the value added. Are they ever an option for going back to (even on a lesser deal)?
