Short answers, pulled from the story.
Street Fighter Alpha 2 Gold emerged as the only exclusive title in the 1997 compilation, a version that never saw release in arcades or on other home consoles. This specific iteration, known as Street Fighter Zero 2 Dash in Japan and Street Fighter Alpha 2 Prime in Europe, introduced Cammy to the Alpha series for the first time.
The compilation brought the Super Street Fighter II games directly from their original CPS II arcade hardware to home consoles without the usual compromises of the era. Players selecting either game from the title screen were immediately transported to the attract mode, preserving the authentic arcade experience down to the sound effects and frame data.
Critics in 1997 were baffled by Capcom's decision to include Super Street Fighter II, a title widely regarded as one of the weakest entries in the series, while omitting other beloved iterations. The compilation was judged to be too weak in its selection to justify a purchase, with many reviewers feeling that the inclusion of Super Street Fighter II Turbo was insufficient reason to buy the collection on its own.
Kelly Rickards of Electronic Gaming Monthly scored the Saturn version half a point higher, arguing that the Saturn controller was much better suited to fighting games due to its layout and button placement. His co-reviewer, Sushi-X, gave both versions equal scores but noted that the PlayStation version was slightly better because the Saturn version suffered from some visual glitches.
Street Fighter Collection achieved a remarkable level of acclaim at Electronic Gaming Monthly's 1997 Editors' Choice Awards. The compilation took home the titles of Fighting Game of the Year and Best Compilation, while also earning a runner-up position for Saturn Game of the Year, losing only to Saturn Bomberman.
