1 was fine, although i feel like it just lacked some things
2 was ok, i didnt know what was going on and the ending was horrible
3 was perfect. I knew what was going on and it just had a nice feel to it. Presented well. ALSO CUSTOM GAMES
4 was ok. Although I dont like it since it was made purely to make money and not tell a story. Multiplayer is stuff with all the doritos and mountain dew bullstuff with double xp and season pass. Ugh.
Reach was fine, although they improved forge but nobody played custom games with it. It's a real shame :(
ODST was stuff. There was no need for it. At least it came with all the map packs THAT I ALREADY BOUGHT BEFOREHAND
Wars was blegh just because its an RTS. I dont like RTS games. At least they branched out a bit, i guess
Basically, they only should have made 1, 2 and 3. The rest should never have existed. But nooo, microsoft must milk it for all it's worth
