Okay for those who will be getting an Xbox One soon I have being looking at the current games released and I believe these games are the ones I think GL members should get.
1: Destiny (Due to a major amount of current GL members on XO play it)
2: Halo: Master Chief Collection (All 4 main Halo games plus Halo 5 Beta)
3: GTA V (Cause it's GTA)
4: Warframe (It's free)
5: Minecraft (Only $5 I believe for those who have it on 360)
Also future games such as The Division, Halo 5, Space Engineers and others will be main GL games. Also during playing Destiny I met a friend called Wolf and he is interested in joining GL. His a stealthy type of player which is good for Silent Blades
