I would do it as option 2, where the main disco info would just have a 
feature of "http://jabber.org/protocol/games", then if people want to 
retrieve a full list of the games you support they would do a disco#info 
query on the special node for games (http://jabber.org/protocol/games), e.g.

<iq from='romeo at montague.net/garden' to='juliet at capulet.com/balcony' 
id='req1' type='get'>
    <query xmlns='http://jabber.org/protocol/disco#info' 
node='http://jabber.org/protocol/games'/>
</iq>

<iq from='juliet at capulet.com/garden' to='romeo at montague.net/balcony' 
id='req1' type='result'>
    <query xmlns='http://jabber.org/protocol/disco#info' 
node='http://jabber.org/protocol/games'>
        <feature var='http://jabber.org/protocol/games/tictactoe'/>
        <feature var='http://jabber.org/protocol/games/chess'/>
    </query>
</iq>

This allows easy use of disco without bloating the main response.
