7     sharks: Marvin Harrison (39)                                                                     7     33333-One of the issues is that im forced to do a group by 'event_code_num' whis is in turn causing the issue, but i needed in the output.
-Second issue is concatinating the results of players that scored more than once in the game like Marvin Harrison, above
-Third issue is that i want to sort the time in asscending order in the output of game_stats, like so Marvin Harrison +(26, 30 pen, 38,44 pen)+ and i want the result set to be sorted by home_team first followed by away team for each game.

Answer 1

I've gone ahead and added notes as you had suggested frank, and thanks for the suggestions in regards to genral coding!!
Table Columns/Defenitions:
time : the minute during which a player scored
game_date : the date of the game and time at which a player scored
team_id : the teams id
home_team_id : the home teams id
away_team_id : the away teams id
home_team_name : the home team name
away_team_name : the away team name
offensive_player_moniker : offensive players first name
offensive_player_last_name : offensive players last na,e
play_result_id : the number of play that resulted
7 = Scored
event_code_num : the code number for a type of an event
11 = Scored / 17 = Penalty / 19 = Scored in extra time
game_code : the code of the game
DESIRED OUPUT
You were right my desired output was incorrect here it is again
bombers: Chris Carter (32) 7 11111
parks: Steve Smith (39) 7 11111
sharks: Marvin Harrison (26, 30 pen, 38, 44 pen), Bob Sanders (30 pen) 7 22222
carts: Marty Booker (35 pen) 7 22222
carts: Marty Booker (38 pen) 7 33333
sharks: Marvin Harrison (39) 7 33333
Breakdown of output:
sharks: Marvin Harrison (26, 30 pen, 38, 44 pen), Bob Sanders (30 pen) 7 22222
sharks = team name
Marvin Harrison = player name
(26, 30 pen, 38, 44 pen) = ascending order of minute at which player scored/commited penalty
***Note*** the 'pen' after after the minute value signifies that the player commited a penalty at that minute, (event_code_num = 17)
'7' = play_result_id
'22222' = game_code
Explination of code
