Ok so I think we all know these 4 games have certain distinct game mechanics which caught our eyes. To start it off GW2, I picked the "Dynamic events" mechanic just 'cause when I heard quest just randomly go to you thats when I thought "I might play this game". Next we have SWTOR and the Bioware "mmo storyline" I do remember playing wow and just grabbing quest but when a lore conversation was started in guild I had nothing to say. So no reading? F$%& yeah. Then moving along to Rift, "The rifts of Telara" this one was also an ear catcher but I just had a feeling I wouldn't like rift. Last but not least sometimes, Wow and their infamous NERFBAT(Nerf everything! make content easier!) haha I kid. TBH I don't know what game mechanic they pioneered, So if you could inform me that would be cool!
If you see any mistakes or think there is a better mechanic from a certain game that you think I should have used instead. Feel free and let everyone know.
