well as i played the game i saw 2 things that would imply there should be more episodes.
1.- The relationships between the team and 62(i think it was, played it so long ago) are not as well developed to actually come to an ending + there is the situation with the scouts and the crush anon has on kourtney.
2.- Sector X (if im not wrong) the plot there was not finished as it ended on some cliffhanger about asking for a transfer?(lending? smt) of numbuh 62 to their sector.
those things imply some kind of episode after G.A.M.E.N.I.G.H.T to tie those things down unless they just ignore them or just decide not to follow them to fruition.
but we can only hope. and im sorry if i said something wrong as i played it like months ago
