While the OP meant it the way he answered you, the way I see it used most often colloquially is that when someone or something does the heavy lifting especially in gaming, they are providing the bulk of the work. Like doing the heavy lifting in a team game equates to carrying the team, or saying a character does the heavy lifting instead of the player, means the character is overpowered and carrying the player (or vice versa).
The game is great and easily the best japanese fighting game experience for casuals. (Mechanically I prefer anime fighters though.) For once a Japanese game has all the bells and whistles instead of almost purely focusing on the multiplayer.
The cosmetics are what they are. At least it’s not p2w but it’s up to consumers to not spend if they don’t agree with paying more in a game they already bought.
Edit: downvote me all you want but the truth is that street fighter 6 was a very big step forward for japanese fighting games in terms of what they offer consumers. The fgc hasn’t had games that can truly appeal to and bring in new players so I can’t help but be happy for it. The only exceptions would be NRS’s games and smash.
