mg_mythology_island_beta - no for now, reports of lag due to expensive shrubbery.
mg_grands_multigames_2013_fix - No, the multigame maps we have have the same games.
mg_airforce_marines - We can try it, I worry about lag and vehicle issues even though the mapper claims there are none (I've seen multi vehicle maps before and they are not good)
mg_100traps_v3 - Seems a bit boring to me but we can try it.
mg_smee_tower_fix2 - A classic that I never cared for but I'll add it.
mg_across_the_street - I'll give it a go.
mg_velocity_tower_v3 - We'll try it.
mg_neox_multigames_pbeta2 - Has alot of the games on the other multi-game maps, so no.
mg_kennys_multigames_x2 - Theres porn content built into the map, so no. Too bad cause this had other games.
mg_awp_submarine_v2 - Will try, may be OP with AWPs.
mg_frightnight_final_v3 - Sounds interesting, will try it out.
mg_thc_lego_multimap_v3 - Will wait for fixes.
mg_funmatrix_reloaded - Will try.
mg_creative_multigames_v9_ns - Has issues with configs, we already have enough problems with it now.
MG_SG_Allinone_Skill_V2 - I'm not up for putting harder maps on this server till it can maintain a population.
mg_dream_xmas_edition_final - IMO, crappy map.
mg_car_survival_v4 - Too simular to one suggested earlier, if more support then I'll add it.
mg_somethingfun_v4 - Nothing new to what we already got.
mg_fun_multigames_fix - We'll try it, it looks to have different games on it.
mg_WarmCup_Headshot - We'll try it.
mg_pauls_multigames_v2 - Has a few different games in it.
mg_gravitycastle - I don't understand this, seems kinda DMish if it gets enough support I'll add it.
mg_jurassik_island_v1 - Vehicles glitchy.
mg_multigames_lawr_v8 - Too much of the same.
mg_n64_goldeneye_v2 - Just a multi-map DM map.
mg_ski_mountain - I'll add the normal one as no need for duplicates. I hate this map btw.

I'll work on getting these added over the next day or so.
