Game processing system, method of processing game, and storage medium storing program for processing game

1. A game processing system for processing a game having a first mode and a second mode, the system comprising:

a storage storing a game parameter relating to the game; and

one or more computer processors,

wherein the one or more computer processors execute computer-readable instructions to:

provide, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

provide, in the second mode, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player;

update the game parameter in accordance with progress of the game in the first mode; and

update the game parameter in accordance with progress of the game in the second mode,

wherein a game item is used both in the first mode and in the second mode.

2. The game processing system of claim 1 , wherein an action of the virtual character in the second mode is determined in accordance with the game parameter.

3. The game processing system of claim 1 , wherein

the storage stores scene data relating to each of a plurality of game scenes constituting a game scenario in the second mode, and

the one or more computer processors select a scene to be executed in the second mode from the plurality of game scenes in accordance with the game parameter.

4. The game processing system of claim 1 , wherein the one or more computer processors update the game parameter when the second mode is terminated abnormally.

5. The game processing system of claim 1 , wherein the one or more computer processors performs a switch process to switch from the first mode to the second mode such that a value of the game parameter as of an end of the first mode is equal to a value of the game parameter as of a start of the second mode.

6. The game processing system of claim 1 , wherein the game item is used by the virtual character in the second mode.

7. The game processing system of claim 1 , wherein the game parameter is updated responsive to performance by the player of a predetermined inappropriate action in the second mode.

8. The game processing system of claim 1 , wherein the game parameter is a player character parameter relating to a player character used by the player.

9. The game processing system of claim 1 , wherein the game parameter is changed responsive to either one or both of switching from the first mode to the second mode and switching from the second mode to the first mode.

10. The game processing system of claim 1 , wherein the game parameter is updated responsive to a first action by the player in the first mode.

11. The game processing system of claim 1 , wherein the game parameter is updated responsive to a second action by the player in the second mode.

12. The game processing system of claim 1 , wherein a game item parameter is associated with the game item,

wherein the game item parameter is updated in accordance with progress of the game in the first mode; and

wherein the game item parameter is updated in accordance with progress of the game in the second mode.

13. The game processing system of claim 1 , wherein a game item parameter is associated with the game item,

wherein the game item parameter is changed responsive to either one or both of switching from the first mode to the second mode and switching from the second mode to the first mode.

14. A method of processing a game having a first mode and a second mode with one or more computer processors executing computer-readable instructions, the method comprising:

providing, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

providing, in the second mode, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player;

updating a game parameter relating to the game in accordance with progress of the game in the first mode; and

updating the game parameter in accordance with progress of the game in the second mode,

wherein a game item is used both in the first mode and in the second mode.

15. A non-transitory computer-readable storage medium storing a game processing program to be executed by one or more computer processors for processing a game having a first mode and a second mode,

wherein the game processing program causes the one or more computer processors to:

provide, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

provide, in the second mode, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player;

update a game parameter relating to the game in accordance with progress of the game in the first mode; and

update the game parameter in accordance with progress of the game in the second mode,

wherein a game item is used both in the first mode and in the second mode.
