If there is a way to play the full game w/expansions online (I haven't even played em all, last I got to play was Cosmic Conflict. The hazard deck was sick. I used to play like 4-10 games a day when I lived with board game hippies. We eventually sleeved up the cards and added homebrew stuff every once in a while and came up with some neat mods like draw 4 alien cards, either shuffle or pick the order and you have a different alien for whatever number of foreign planets you have. We'd also do double powers or have an alternate to tech to research where you could also choose to research the alien flare card for your guy to get a permanently playable same alien flare. We even figured out different costs for different flares. Either Diplomacy or Cosmic Encounter are to me The Game of Games. For the total opposite reasons, Cosmic Encounter is about risk management and awareness and counting cards with like 5 decks and an absurd amount of variables as well as the whole negotiation card factor. I will defend to the death that lying is totally allowed in the game because it comes with the repercussions of the table seeing it and it'll effect your game later on, in this case it was final turn, 3 people were at 4 planets , my attack cards sucked but I could at least muster ships to match the defender who was also 1 planet away and the person who was up next was also 1 away. So I asked the defender of they happened to have a negotiate card and wanted to split the win, hid turn wasn't up for a bit and the next person up was probably gonna take the w and I didn't have s prayer for solo cause I only had like a -2 and a kicker with my negotiate and literally showed my hand. He agreed to the negotiate and I won off a -2 card and 3 ships.
