Here is a rough draft of our usual topology. Imagine a few more
"Players" section scattered around the 2x10G rings.
We are already planning for IPV6 but that really depends on our upstream
ability to actually provide the feature. Very good point about BCP38,
that is not something we had considered. We usually segment the network
for each row of tables which usually ends up being 48 players in the
same vlan.
Thanks!

We were looking at either the Nexus 7004 chassis or the ASR 9004/9006
chassis as the core "switch". We would then use 48xGigE and 1x24 SFP+
line cards. Our actual port requirements and somewhat flexible but we
do need at least 4x10G Fiber ports. And at least 48 GigE ports for
players or access switches.
I don't really understand your topology. 2001-2004 I was involved in
providing network connectivity to around 2500-4500 users at Dreamhack,
back then the largest LAN in the world as far as we knew. Back then we
made do with 2x100FE for 20 computers and the core connectivity was
2xGE. I'd say your design seems to fairly similar, but with 2x10GE
instead, but I'm just guessing from what you wrote.
ASR9k has been used before and will do just fine. Dreamhack has grown
a bit since I was involved:

I'm also open to any suggestion within Cisco portfolio. Our needs are
pretty standard and nothing extraordinary but we would like to use
this opportunity in order to try new equipment and technologies that
are usually only seem within ISP and large networks.
Don't forget to provide dual stack (IPv4 and IPv6) connectivity. Limit
your broadcast domains (I'd say 20-50 users per broadcast domain), and
make sure you do antispoofing (BCP38) for everybody.
