To be honest, free Destiny 2 isn't very useful. To play Destiny games, you must keep up with the DLC expansions. If you don't pay money for the expansions, your experience is limited to low level loots and low level activities (which you won't find other players to play with cos they only yield low level loots, not to mention that they tend to remove existing contents with new expansion releases). The base game might as well be free-to-play bait to make you buy the expansions. And buying the 3 expansions separately ($20 for the first 2 together, $40 for the upcoming third) costs the same as the latest bundle of base game and 3 expansions (at $60).
I have already played everything I want to play during the recent free play weekend (all story campaign, all contents except raid/nightfall and such cos I only played solo, and it was level capped, so the expansion stuffs were not accessible even though they were there).
If you didn't participate during the free play weekend, it is still worth playing through the campaign. The gun play is still very shiok. But for longer term continued progression, you need heavy commitment in money and time.
PS. Foul Play is nice, a beat 'em up with unique setting.
